why is it when i build a perfect symmetrical car and trusters

and go in the air the car or stucture tends to tilts, banks and rotate
i know it should phisical but still

i tried to use other trusters to use to counter those emovement
at first i tought it was because of the rag doll but when it falls forward
i still tilt backwards i can use a few more bars in the front part for ballance
but eventualy it still banks again

a plane going forwards in the alr somehow always banks to the left

So, reinstalled the latest version on my Win 7 x64 machines. No problems before, but now it freezes on the loading screen as soon as I launch it.

Vehicles created before Version 0.4.8a wont load at all.

Download and launch Crashtastic.exe, get error:

The application has failed to start because its side-by-side configuration is incorrect. Please see the application event log or use the command-line sxstrace.exe tool for more detail.
