I'm having some problems getting RimWorld to launch. I've played ~30 hours and I've launched it several times without error, but most recently it launches to a blank screen and stays that way even after letting it sit for an hour. I'm wondering if I should just reinstall, but like an idiot I've deleted the installation launcher, AND I cant figure out how to get back to the page that lets you download another one of the limited use downloads. Help?
