I'm using Win 7 HP (64) and have had nothing but trouble with Media Player 12. I have a large library (over 4000 songs) and it just can't handle it. It worked ok to start, imported the songs and 75% even had the correct artwork. I then went to add the missing artwork and discovered the every single song was duplicated. I closed the program and restarted. Now all my music had gone. It then started to import again. I added the missing artwork without a problem this time around and listened to a few albums. I then closed the program and logged off for the night. Next day, all the music was missing again. I folllowed advice here about managing the library, removing, resetting etc. Added all the songs again, got duplicated again then lost the lot. I have now given up with it and am using Winamp. So far, this has been great, even the artwork is there. I'm pleased Winamp works so well as I didn't want to have to go back to using iTunes. So, is Media Player 12 really that buggy? Is there a fix for it's flaky running? Cheers, Pete.
