My FSX is glitching bad, can someone help?

Hey guys I noticed after I flew a couple times that my sim goes nuts right after I rotate and climb on the RWY HDG. I know theres Left turing tend. but my wings and entire aircraft just rolls over to the left.
also another thing, in fs9 my CHFlight Yoke and Pedals were fine, but now when I fly stright and level, it wants to go to the left. its like the sim doesnt want to do anything I want it ta do. COULd SOMEONE HELP ME PLEEEASE this is really frustrating me cuz I need the sim to practice for my IFR lessons.
Thanx
Bret
