erm....big problem....need help guys....
one day suddenly i cant use WINDOW MEDIA PLAYER to play a simple mp3(any mp3 extension file)
but other software such as winamp,real player,media player classic work just fine...
one more thing,my window media player can play other file such as wav,avi and any other extension except mp3 files....

it keep on show up error message in window media player "Windows Media Player cannot play, burn, rip, or sync the file because a required audio codec is not installed on your computer."...

What i've done:
1) uninstalled window media player & reinstall it
2)install K-Lite Codec Pack

but the message still come out when i use window media player to play mp3 files...

i tried to uninstall both and reinstall both still the same problem!!!!
