Amsterdam gives fatal errors if you have acceleration?

Yep, so far happens 100% of the time at night.

Amsterdam isn't that bad for me.. but it's still below the quality found in the Simwings addons. I don't worry about Aerosoft too much, eventually they all get fixed to a point where they are usable. But I think they need to work better with outside developers especially for their first release. Take a bigger cut and do 1/4th of the job but get it right, then let them loose on their own. This is obviously the kind of thing that OrbX does better....
