Can you take a screenshot of what the error says?
Upload it to the bugtracker HERE. Failing that, even a screenshot here would help.
The bad news is that it's likely I won't be able to fix it. I had an SSD failure where all the game files were stored and couldn't recover everything, so this version of the game can't really be updated.
The good news is that I'm doing a full rebuild of the game before progressing to the next Phase, so hopefully whatever is causing your crashes should be fixed as well. But being able to see the error should help to remove the problem if it's not something already fixed.
