Reinstalled .net, .net servicepack 1 and the application but the problem is still there, i don't have problems with other programs. I've had the same problem about a year ago with some keygens, i couldn't see the text in the buttons. I've found a way around it, i just press some buttons and they reappear as i hover over them or press next and then back. I've just installed and updated windows and it's the full version (nothing removed with nlite).
