have you tried calibrating it with the contol panel?

 

yea and that didn't help. i don't know what it could be i had the problem once before with UT and someone helped me fix it but i don't remember how.

 

i tried calibrating the controller then testing it in my control panel everything worked fine then when i get back into my game the samething the controller still moves on it's own down and to the left could this be a binding problem with in the game and if so how whould you fix it cause i tried running ut and it does it in unrealtournament i can't remeber how the last person helped me with this i know it can be fixed i think
