Did you chose a s/w version or did you let your program decide for you?

I don't think there is a way to roll back. When a new version is released, the old version effectively is deleted. WinKFP might be able to over-ride that.

Try checking for other data, maybe you need adaptations reset, or throttle initialisation.
Often just switching on the ignition (run position, engine off) and letting the car sit for 30 secs will allow it to readapt the throttle position sensors.
There should be a code though, something like throttle adaptation not complete or interupted.
