Game Video Display Too Large 4 Screen

Suddenly my in-game display is huge! It is so big, that I cant see on the "friend" or "settings" buttons at the top right. The game is unplayabe so please help!
every other application display is normal - only cf is huge.
this is what I have tried:
uninstalled game, reinstalled.
changed in game video settings - windowed mode seems normal but it is too small.
updated video card drivers (already up to date)
changed grapics display mode (made everything horrible).
adjusted monitor settings (changing size and position of display).
Searched forums for a thread -saw nothing.
Help me now please!
I love you guys.
