Since there's no help forum for TSM, I'll post this here. I've been getting this message every time I've tried to open the launcher. Even when after reinstalling twice, it still doesn't work. Besides this, in game, whenever I try to create a sim, the game never loads after exiting CAS. What could be wrong? Nothing like this has ever happened to me
