Is it the first time you launch the game ? Or is the game used to work fine before on the same system ?
It was working fine the first day I downloaded it, and then I saw the behavior I described the next day. However I just checked again and it seems to be launching just fine now after a few days of definitely not launching. Unsure why. Anyway, I'll keep an eye out in case the launch failure comes back. Are there any generated files Voidrun creates that might be capturing error messages?
