Heh. Without reading all the posts - you CANNOT reset adaptations with the engine running. It even says so right on that screen. That was the original source of his problem.

What is less understood is the reset will pretty much always cause a rough running/error code after the first start (which is why i guess the OP tried it with the engine running). All you need to do is clear the code and it will be fine after the next start.

Basically it goes like this:
1. With ignition on (but engine not running) reset all adaptations
2. Start up. Clear errors.
3. Upon 2nd startup all errors are gone and engine runs normally.

It seems like "black magic" but trust me its not.

FYI, if you clear adaptations it also resets emissions monitors. Do not do this if you need an emissions test relatively soon...
