Rigid Body simulation is not working as planed

Hi there, I’m new in Blender and tried to setup a Rigid Body Problem. Everything runs fine till I want to add a new RB, then the simulation stocks. It stocks also when I remove the new added RB.
Has somebody an idea what the problem can be? Thanks in advance.
Now I see that as a new user I don’t have the possibility to upload a file.
Well maybe somebody can help. Thanks.

You can upload your file to pasteall.org.

I tried, but -> Site Not Found

Strange it works for me…

I hope it worked: file B00_02.blend

I found it aout: The Transform Lock was set, when imported the new part - automatically. After unseting the Lock, the modell works as desired. Nevertheless thank you.
Kind Regards
