My Fraps Crashed

Whenever i play TES IV Oblivion with my fraps activated at the start of gameplay it always crashes so i cant share my adventures during my gameplay. I dont know why's the problem. I tried lowering the graphics but it crashed again then i restarted the game played it and again it crashed. I searched the game for virus but there were no results then at a later moment i tried deactivating fraps and it worked, the game did not crash, so the only thing that makes the game crash is the fraps. Too bad i have to use screenshots but i cant use the Alt-Tab option so if i have to use screenshot i have to exit the game to save that screenshot which i will not do because that would consume a lot of time.
