Cannot use Fetish Nightfall 4.1 - no error messages though?

[Cybermik]

Hello all,

I installed version 4.1 three days ago - I can load it ok in game, and there are no error messages - BUT:
all windows are bright yellow, the text must all be the same color, because I can't see text in most windows.
Also, cannot see text in pop-up windows (must be yellow-on-yellow)
Any ideas what I can do??

Thanks
