I PM'ed you the dxdiag igazor :)
Yes, the exit to main menu crash is instant, no matter the play time. I've even tried opening a fresh new town and then pressing it and it will crash. Other than this and the travel crash, my game runs perfectly fine, I can even save and save as without any problems. As long as I stay in the same neighborhood (no Uni, World Adventures or 'move neighbourhood' and never press exit to main menu then all is well. It's just... very odd.
EDIT: I hope this isn't a fluke but after disabling UAC and restarting my PC, I can now exit to main menu without crashing. I've tried it on my current save and a brand new one in a different world. I'm also now able to travel on vacation and attend Uni (I did download NRaas Traveler, Overwatch, and ErrorTrap), I haven't tried moving neighborhood but I'd hazard a guess that it should work also now. :)
