Can't play MPEG & MPG Files

My Windows Media Player 9 suddenly can't play both mpg and mpeg files. So I reinstalled Windows Media 9 Series Codec but still can't play. I searched through the net but can't find any solution. Does anyone here has any possible solution? Please reply. Thanks!

What error messages do you get?

I attached the screenshot

have you tried reinstalling the media player. the file you are trying to play a different file because the file you are trying to play might be currupt. if noting works i suggest you un-install and then reinstall it again.

you can download it from:

try the codec pack from k-lite .... has all the codec's needed when I ran a windows machine :)

Try viewing your files with divx.
http://www.divx.com/

Its free for personal use. If it doesnt work, then the file is corrupted. Do you get the same error for all your mpg/mpeg files?

--edit--

Try out penguin's suggestion first (never saw his post -.-).

I have checked all the mpeg and mpg files, but all can't play. I reinstalled Windows Media Player , but can't work either. I will try out Phat_Penguin suggestion.

I tried the K-Lite Codec Pack and play the files using Windows Media Player and the Media Player Classic included in the K-Lite Codec Pack, but still don't work Zzz...
I attached the error screenshot when I try to play it in Media Player Classic.
Anyone know of any other solution?

Err.. Try press the "look for codecs on the internet" button..
