I tried to open a drum map but,none of the presets were there.I found them on my hd and tried to open one,when GTP4 opened,I got a message that said "The file you are trying to open is not compatible with this version Guitar Tracks Pro". All of the file names were blue and they use to be black.

I reinstalled GTP4 and updated and still got the same message when I trid to open a drum map.The drums worked when I first installed GTP4. 

  Problem solved,tech support pointed me in the right direction.
