I have gotten messenger as a replacement to MSN.  I have my Yahoo ID, which works on mail and I have downloaded both Beta and 7.0 versions of Messenger.  I have played with the proxies and still it will not let me sign in.  At worst the sign in screen settles into an alternating pattern of yellow ball/purple ball at best it tells me I am sign in on another computer (which is butkiss as I am not) help!!!!

for some reason, the service might be down. if not, try to check your firewall and configure it to allow all connections for yahoo messenger. Also, u could try a clean install of our yahoo messenger on your pc.. uninstall and install the latest version.\n\nbut i think its because of the service is down.. but however, good luck in trying my solutions.

It sometimes does that. My girlfriend has had problems with it for a long time now. It will just sign you out automatically when you didnt do anything and sometimes you cant even log back in.\n\nYou can always download and install the older versions, dont fret =)\n\nJust go to http://www.oldversion.com/program.php?n=yahoo and you can just uninstall the new one if it continues to give you problems and get back the older ones.

ugh, you dont need to download it again, unless you want to be signed in to two accounts at the same time, then use web messenger. you can use as many accounts on one messenger as needed, but you can only sign in one at a time

This also had happend to me when installing the newest Yahoo Messenger. after a while it started working. but until then you can use other messenger programs to connect to the yahoo service and IM other friends.\n\n1.Trillian\n2.Miranda IM - http://miranda-im.com/\n\nOr try  using a Older Versions\nYahoo Messenger 7.5.0.647 - http://tinyurl.com/zo7n9

This might not help, but trying won't do any harm...\n\nOpen your messenger and click on preferences (or hold Ctrl+Shift+P), and select the connections option.\nIf it's set to No proxies, change it to Firewall with no proxies, then select your connection settings, press apply then try to connect again.\nIf this doesn't work then try playing around with the preferences, but remember to return it to the original settings if nothing fixes the problem.\nIf all else fails, uninstall and re-install again, and if that fails contact Yahoo messenger help (F1 in messenger).\n\nGood luck!

I used to have problems with the older versions of msn messenger but i got the 7.5 version and its quite good. It can be sometimes a problem if you have quite a problems loaded up plus your internet/broadband speed will have an effect. Hope you sort it out soon i know how frustrating it can be! I would download a new version and reboot x

Just as a test try to make a new user account with yahoo messenger an seeing if that helps ( If not then go to a friends place and try and sign into yahoo messenger ( If it works there then they may have blocked you from logging on by your ip address or something to that extent ) So may be worth while contacting your ISP and seeing if they can change your ip address or something like that.

Here are some suggestions you might want to check/try: \n1.  The date on your computer needs to be set properly -- double click the clock verify that \nthe time and date are set. \n2.  If your password information is not saved, verify that you are typing it in with the \ncorrect case (uppercase or lowercase). \n3.  Change your password @ http://memberservicesnet.passport.com/memberservice.srf, then try \nsigning in again. \n4.  If you use a firewall (like ZoneAlarm, Norton Internet Security etc. ), it's possible \nthat Messenger doesn't have the correct rights to access the Internet, especially since you \nupgraded.  You may need to re/add Messenger to the allowed list of programs in your firewall \nif this is the case. \n5.  If you disabled your firewall in the past, it still may be blocking Messenger -- try \nrestarting it and see if that helps the situation.  You also might try uninstalling an \ninstalled firewall, to verify that it isn't causing a problem (even if it is disabled). \n6.  Clear your IE cache and cookies -- open Internet Explorer, click the Tools menu, then \nInternet Options, then click the Delete Files button, and when that's complete click the \nDelete Cookies button. \n7.  Check your IE Security settings -- open Internet Explorer, click the Tools menu, then \nInternet Options, then Advanced tab, scroll to the Security section, and verify that "Check \nfor server certificate revocation" is unchecked.  Also verify that 'Use SSL 2.0' and Use SSL \n3.0' is checked, then click OK. \n8.  Click Start, then Run, and enter the following: \nregsvr32 softpub.dll \nthen click OK \nThen try again\n\nAny computer problem\nanswer by expert join our group \nhttp://groups.yahoo.com/group/prithvionline

Yahoo switched off their Java chat, so now you have to use Messenger to connect.\n\nhttp://chat.yahoo.com\n\nWith the change, their servers are probably overloaded.  Hopefully, the problems get sorted out soon.
