Windows 7 Having problems with mp3 tags in Windows 7 media player 12

[coolduedkunal]

Previously I was using Windows media player 11 on windows XP. I edited many of the mp3 tags from windows media player 11, advance tag editor. Recently I upgraded to Windows 7. Now windows 7 or wmp12 does not show tags only which were edited from wmp11 and it is able to show tags which were edited from other media. Also wmp12 or windows 7 does not allow to edit the tags of the same files.

Please help!

Thank you in advance.
