The problem is reproducable. Every time I click on run on the modified model I get exactly the same error. The funny thing is the exception popsup but I can click again ok and run and the simulation goes on. But after a few minutes I get again the same exception and then VC Crashes.
There are some similar posts on the forum but for my case restarting the computer did not help.

And I am not sure how to check which component has the Problem, since it is a quite big layout and the error message is not very helpfull.
