Im getting a crash without an error-message when entering the institute.

I can't load my savefiles where my character stands inside the institute.

And I can't enter the institute with the teleporter. (It's my first time entering the Institute)

The quest I am doing right now is "the molecular level", if that is important.

The problem seems to be similar to these in this thread:

I'm playing on Pc and I allready tried to use the beta-patch on steam.
