i'm not completely sure, but i think you prolly needed to export your main char to the character file and copied that over too.
that's the only thing i can think of....unless you accidentally left out one of the files from your savegame folder. there's usually 4 non-character files in it, and then one bmp file for each character. mine are full, so i have 10 files in mine.
the install of the game on you lapper is the same as the one on your desktop, correct? and your lapper has all updated drivers, both sound and visual?
i wish i could be better help.
