Cant take off, Plane keeps turning left!

[nextokkin]

Hello, Ive been playing flying games for quite awhile but ive never seemed to have this problem. When i start my engines and start moving the plane seems to want to pull to the left. So first thing i think of is the rudder i checked the settings making sure none of the keys where messed up under controls. Next thing i thought that it was my joystick...So i log off the game and log into another flying game. And nope...it doesnt pull to the left. So then i logged back in and tried the very first training misson where your already flying to see if the rudder was pulling to the left and it wasnt...So it seems that im doing everything correctly but while im grounded and trying to take off the planes seems to want to pull to the left. Which makes it impossible to take off. Im open to all suggestions i would really love to play this game and i would like to know that i didnt waste 50 USD on this game.
