I updated my WMP from 10 to 11,when it says install complete, i
restarted my computer. When it loads to windows, a pop up windows
appears and says that unregmp2.exe application was not able to
start becos WMDRMSDK.exe was not found, then i google and dled some
dll and the 2nd time it says MFplat.dll was not found, then i
downloaded the dll again. After everthing, it says i must be an
administrator to complete the installation....
but the problem is that when i rollback to my WMP10, i update
again, it says WMDRMSDK.exe not found....
ok......wad do i do now? other than use winamp, VLC, itunes
i wan see see WMP 11 
bloster is so confused
