Just curious, are you playing on a older computer that doesn't support 64 bit applications? I probably should have mentioned that it's 64 bit only. I haven't messed with it much, but I think I could release 32 bit supported apps if that would help? Is there any way to generate a debug log? Maybe that would provide some more info and make it easier to fix.
The terminal pop-up is totally normal and there's nothing to be afraid of. It just means that the game is doing a lot of start-up processes and your computer wants to keep you updated in case it takes a minute or two.
