Can't search a specific track on usb key(solved)

Hello everyone!
I've got a little problem with Cross DJ 2.0.1 on a PC.
When I plug my usb key into the computer, Cross DJ recognizes it, sees my folders, but when I'm at the root of the key and that I type in the name of a DJ or a track in order to find it quickly, it looks like Cross DJ can't look through folders...
I need to be inside a specific folder in order to search something inside that same folder, not really convenient when I don't remember where every single track is...
Virtual DJ does that in a really good way, and I think it's kinda weird that Cross DJ doesn't...
Any help?
