Recently I upgraded the operating system on my computer from Windows Vista to Windows 7 home premium. After installation of the operating system I am facing some problems while adding some files to Windows Media player 12. When all the songs are added to the Windows media player 12 library, most of the songs go to the folder named "Other media". I am not able to move these files to their respective albums. Some files from these folders play fine but sometimes Windows Media Player 12 displays Other Media File error for some songs. I cant figure out why I am facing such problem and hence need your help in solving the issue. Any suggestions about the topic are more than welcome. Thanks in advance.
