Railworks America

when i try to use the thorttle it goes back to 0

What scenerio are you running? Some of them have the default start up with the trainline set in emergency. You will have to do a release and let your air come back up. I set my independent up, release and build air. Takes a couple of minutes. Then apply throttle. Hope this helps.

nope all of them go back to 0%

i gtryed i maybe have to reinstall it

Done the usual stuff? Cleared blueprint cache, verified game files? Are you using that stupid Fisher Price F4 HUD, or the F5 and F3 HUDS? Keyboard and mouse, because Raildriver doesn't work with a lot of trains/ routes/ scenarios.

i cleared the blueprint cache but no difference i even reinstalled it

is my railworks outdated it is: v11.7b
my freind james says it is
