Crashes after first load

[AstronautMario]

The game works fine for the beginning until it loads the next map, it freezes up and crashes. I have the steam version, and when I first got the game, it was working great, now after reinstalling it, crashes after the first load. What can I do?

Perform a Steam File Integrity Check, then try again. If that doesn't help, post the hpl.log file. If you need help with these steps, check Problem I and X of the Troubleshooting Guide here: https://www.frictionalgames.com/forum/thread-3754.html
