When I press New Simulation, the program gives this error, and crashes: Runtime error 339, and then says COMCT232.OCX is not properly registered or something.... I tried manually registering it, running installer as admin, etc, etc, but it still doesn't work. I downloaded the library from another post, registered that, and it still didn't work. And yes, I'm running Vista. -_- 32-bit, if that matters...
