Ok, one thing to do is go to ghub and click on the nr2003 profile in the drop down list, it will say it is active.
Go click on the steering wheel symbol in the upper left corner.
Your steering degrees is probably going to be set at 900, set it on the slider to 360.
Do that.
In nr2003 turn the animated steering wheel on if you don't already have it on.
If you calibrated the steering wheel correctly by turning it all the way left and right until it stopped, both wheels should now match each other.
Next, turn ffb back on and set it to 7% in nr2003. If you turn ffb off the wheel may be hard for non ffb games.
Next in nr2003 go to your options and control tab, next to where it says Control Assignments click the advanced button, where it says steering linearity set that to 75%.
Next is the track that is messing up before turn 1 an Atlanta track, or is it all tracks.
Try that stuff and let me know what happens.
P.S.
I just realized you said you deleted ghub, you need ghub. If you deleted and didn't uninstall it you going to have to reinstall it. By the way keep cool hang in there, don't let it get to you.
