Yes, that's true. You also have to take really care that you don't put files in there that may not be there. So no less but certainly no more files! I had the problem too and i thought that if i copied all files in all directories, that i could not have forgotten one file. But that was the problem, there were too many files in the directories.
You must double check! Hope you can solve the problem.
Ibanez guitars played by people like Joe Satriani and Steve Vai make me wanna go fast!!
