I had Daggerfall running with the WASD keyboard configuration, by changing controls to viewplyr.dat in the z.cfg file.
However, I accidently clicked the "Default" button in the Contols setup, and now I can't get the WASD configuration back, unless I manually change the keys myself.
Just grab another copy of the game and find a good copy of the file. Or maybe a friend who has a copy can send you a proper copy. I'd have already done it myself if these boards allowed file attachments.
