Sorry to hear that.  Try to delete it completely from your computer, then re-install it.

I would start by making sure your system is up to date.  Go to http://update.microsoft.com

Try entering it manually or contacting the Nintendo Support line at 1-800-255-3700. Or try this website http://www.nintendowifi.com/customersupport/SupportHome.jsp

He wont turn yellow till you sign in.  Unless you have the setting that way ( i think its like invisible or busy, or not available...something like that).  Check your password, and try signing in again manually.  Maybe it has an old password saved, if you've recently changed it.

It's possible that nobody was signed in.  Happens to me all the time

I have the same problem! And... I have a lot of trouble signing in initially too... \n\nI reformatted my computer recently and re-downloaded AIM and it still has the same problems... I think its just their program. I stick to Yahoo! It works a lot better.

Sounds like you accidently provided the wrong password when you changed it. Just try logging in through "forgot password." They'll reset the password for you.

I might be way off, but its only letting me in if i use my primary ID. Try that.

You need to go to preferences and unclick the thing that says "start up at sign in."  If you can't find it you can uninstall and reinstall, and that is one of the questions you are asked through the set up.

When you reinstalled did you do typical or custom install? your answer probably is there. \n Did you do a file search? try that 1st  If not there put your ME disc in. Open with explore and locate and install from there.

close yahoo messenger and exit from the task bar also and try signing in again. \nIf that does not work, then try going to "connection preferences" in the messenger menu and select 'no network detection'.\nIf that doesnt work either, then u will have to uninstall yahoo and install it again.
