Re: Leviathan DLC crashing

The AHQ is for "player-to-player" technical self-help and game-play discussions.  No one here is under any obligation to respond to, much less resolve any issues at all.  We're just fellow gamers, doin' the best we can.

That said, your situation is so unusual as to be, perhaps, unique.  The game works correctly for the vast majority of (PC) players.  Even many of those with problems similar to the one you're describing have been able to get it working using the tips and tricks others have posted here.  The fact that your hardware is "so far above recommended" doesn't mean that the offered solutions (lower resolutions, windowed-mode, etc. ) might not have helped.

As for a "... a total lack of customer care for a shoddy product."  The millions of happy, satisified players around the world might disagree.  And the fact that one particular player is unable to get the product working on one particular PC (out of the infinIte number of combinations of hardware and software that can be built) does not support the assertion either.
