Had this text file in my directory - must have been how I fixed it

Hey Scotty,
Don't beam me up scotty LOL but I've got a solution for you. Had the same problem.

Go to the 'regkeys' subdir where you've installed OIB. In this subdir you will find ForceDX7JSOn.reg and ForceDX7JSOff.reg

Execute them and it will turn your throttle on or off in OIB.

Good luck with it.

Hope it works
