Which applications/games are you having trouble with? I will look into it further
I advised reformatting on your other thread (Didn't realise it was you that had queried about it on this thread), but I will try and find a solution around that if you give me a little time ;)
I've got a stuck app and I followed your instructions, taking care to show both hidden and system files. But I can't find either a \sys or a \private folder. What have I done wrong?
Make sure you have the viewing of hidden files enabled - You can edit this from here (Win XP):
Control panel -> Folder options -> (Tab ) View -> (Advanced settings:) -> Hidden files and folders -> Show hidden files and folders
Click 'Ok' and you should be able to view all the hidden files on the memory card. You may need admin rights to carry out the apove method, though I'm not sure
