If you open up media player and click guide, find downloads and then codecs, you can get new audio and video codecs for free from microsoft, that should fix the problem.

Re-download/upgrade it from Microsoft...this should cure any issues.

I have been asking what this was for awhile now. Finally, I deleted Windows Media Player totally off my computer and re-downloaded it, as well I "saved to computer" and now mine works just fine. Good luck!

Check out error messages through Microsoft, butt I think you need to turn off your firewall.  I think I got the same message number, and that was the problem.  LOL

Your question doesn't have enough information to answer. Your error messages indicate your are not playing your music locally. But I'm not willing to rule out the fact they've done some OS hardening. Do you have a specific error ID from Media Player attached is a listing of common ones on M$'s support site. If you do have an ID code and can look at the specific one, they may give you a better idea of what's causing the errors.

Try UN instaling and reinstall see if that helps or play them in the new windows media player 11 beta

hey , i had this prob too, download the divX player, it'll tell you what codec is needed and is a better player than windows, then head over to download dot com and look up audio or video codec as needed and you should be sorted.

I noticed that the first time i did it too. Depends on what your doing..like in my case i had my Xbox 360. I turned on the 360 waited until it gave me something like ur pc cant be found. Then i went to my PC and went to WMP 11, had to download the new official version cause i had both the betas. Then i clicked it and it loaded up something similar to the old Windows Media Connect 2..and you have to click allow to share

I found the error number on Microsoft's technical database. However, it is a generic message and I couldn't find the exact match to the message. I included a link to the page. I hope it helps.
