I've had my memory map for slightly over a year and love it ... til now - it won't go further than the Power On screen. It starts to load fine, but then the slide arrow to turn it on either doesn't move at all, or erratically jumps, either way meaning I cannot get further than this screen. If I then go to the Suspend or Power Off screen it sojmetimes works, but often also doesn't work on this, so it goes to sleep mode and eventually the battery runs flat. Can anyone help? Thanks!
