I have disabled WMP, re-booted and then re-enabled it with no positive
result.
When I try to add files to the library, it tells me that 'no items
match your search' even though I know that there are MP3s in that
specific folder.
BTW it does recognise & play midi & M4a files listed in 'other media'
I had a problem with WMP12 always showing only the default files even
though I had deleted them and added many other music files. I found a fix
here that worked great for me:
This pertains to Vista, but will work in Win7 too, you just need to find
the path to your windows media files which for me was in
Users/Me/AppData/Local/Microsoft/Media Player. I followed his instructions
and it worked great for me. Seems that Media Player's database can get
corrupted from time to time which causes this type of problem.
