A full re-install may not fix your problem which is why I suggested you rename your existing games so keep them safe.... OTOH it may but the fact remains running Fullscreen is "iffy" at best and has not been a supported way to run the game for a few years so if a re-install gets things working for you like you remember.....great..... but personally I don't think it will. You were just lucky to have been able to run full screen at all
