[D.I.N.O.S.A.U.R.]

Well, Ive been playing FFR a little bit today and Im noticing I have some kind of weird event where at the same time of every song, my hits dont register, say 30 seconds into the song. I played Secret Zombie Room like 10 times (since Im a n00b) and at the same point in the song, it would just say miss when Im positive I hit the arrow, but it will say Boo shortly after. Just sayin, I couldve AAA'd that **** (; I just wanna know if it's my computer or what? I downloaded Game Booster 2.0 so no background processes are running or anything. Sorry if I got off topic somewhere. Thanks
