So, the prologue and pretty much everything else works fine, however, the game crashes to desktop whenever I attempt to play Mission 1 - Form the Vanguard.
There are two varieties, one, loading from the 2nd prologue into it "Four Years Later..." Appears, then the game crashes to desktop with no error message, the same error occurs if I select Continue the Story as an option except theres a loading screen with tips instead of the above and the crash occurs once the loading icon disappears.
The other crash issue is selecting the mission itself instead of Continue the Story causes an infinite loading screen that does not end after the tips appear the loading icon disappears and it fades to black - the loading icon reappears when it would normally crash it just.. keeps loading, forever. The icon never disappears or freezes, just continually plays its animation. I've let this go for about 10 minutes without a change so I assume its stuck an infinite loading loop.
Insight into this would be excellent, I have no desire to keep plugging away at it (changing settings, etc etc) just in case this issue is not solved soon and I have to refund.
