I got an error message in the middle of level 5 in D3 Merc which says, "Execution in WinMain() was stopped by an Access Violation." It pops up in a window, and the rest of the game freezes. This NEVER happened until I broke into the laboratory via the lasers. Any ideas?

I just got the same thing, same part. Haven't had any other problems with the game.

Apparently we really aren't allowed into the lab haha

6 years later, I got the same. Still no one broke into the lab yet?

I'll maybe cheat skip level :(

Don't use any weapons in that area, just stay out of sight and use the small black doors (not the large grey ones). It SHOULD work without crashing providing you don't alert the bots by being seen. That seems to cause it to get crash happy.

That worked. Thanks!
