itunes update problems

hey there ,just wondering i received an update for itunes yesterday and i downloaded it.I was using 10.0.1.00 i think and the update was for 10.0.1.22 and since i downloaded it my cover flow is stuffed,when i have it on an album it sits there and flashes different album covers up even when i am not playing anything.is this a known problem or if not is there anyway i can go back to a different version.I have tried everything even deleted and reinstalled itunes.The funny thing is i turned on my macbook pro and opened itunes on there and did not get the update at all
