spoons

i've got an NW-HD1 and when i came upon GYM i thought i'd give it a try. but upon using the program it wipped my database clean. after reading some earlier posts i found out how to retrieve it by changing the name of the back up folder. but the problem now is that when i try to play the tracks it either comes up with "cannot load the rights information from this track" when playing it through the computer or "cannot play track error" when playing songs of the device. is there anything i can do to solve this problem?
