help to restore resolution and fps
You can set the video size again from the Video options when you log in to WoW and turn off windows mode or enable maximise which ever you prefer.
as for the framerate open WFT > config.wft in notepad and look for
set maxfps= xxx
set bkfps = xxx
remove these and you should be back in business.... you can also set screen resolution here but it's probably just as easy to do it in game.
Problem opening config.wtf
just right click the file > then from the menu choose> open with > choose a program > note pad
you can edit right there.
I think key bindings/macros are now stored server side (dont quote me on that) so logouts are more important..
