Hello everyone,  I had all of my WMA's and MP3's in a folder that got
deleted.  I used a few different utilities to undelete the files, however
they no longer play and I get the following error messages:

First error message:
The file you are attempting to play has an extension that does not match the
file format.  Playing the file may result in unexpected behavior.
Second message after It OK
Windows Media Player cannot play the file.  One or more codecs required to
play the file could not be found.

what is missing and how can I repair my files ??  I am running MP10 and
XPsp2.  Same problem on other computers as well, something was removed from
my files when I restored them.

thanks...
