While transferring new games into the device, i accidentally deleted the xmenu.dat icon. So later, when I tried running the whole device again, it said that its needs an xmenu.dat format. So I downloaded one from the net and the next problem was that it required a version 1.45 udisk. I tried downloading it from the net and transferring it into the dslinker several times. But the system keep saying "need udisk version 1.45!" after a white screen appears, any suggestion on how to solve this problem?
