Motor problem

[Singulari7y]

I recently updated to algodoo 2.0.1 from 1.8.5 and when i try to stop a motorized rotating shape with a separate fixated block it goes right through it.If i take the motor of and leave the hinge it will work then.It seems to be a glitch i started a new scene to try and recreate it and i couldn't.It actually worked that time but everything i try to build this happens its a real pain please help.I added a scene with a peace from my latest build that has this problem.

Oh and im using windows vista ultimate x64 with sp2.

500Nm is too much for this density. Increase density or set lower torque (like 5Nm)

Ah right thanks for the reply Kilinich.
