Cant open the game?

[LogLegoMan21]

When I try to open Rimworld, it says "The last time you opened Rimworld by Ludeon Studios, it unexpectedly quit while reopening windows. Do you want to try to reopen windows again?" After I then press "Reopen", it says that "Rimworld by Ludeon Studios quit unexpectantly." When I press reopen, the first message comes up, and it keeps cycling between the two. If I press "ignore", nothing happens, but then when I try to reopen the game, it says the first message...whats going on?

Just to make things clear, are you starting RimWorld in a Windows environment? More specifically, are you starting RimWorld using the Steam client?

I am on a Mac environment, launching it from Steam.
