I think the problems some people are having is..
they are trying to use saves made when the game was v1.0.5, and they've patched to v1.1.5
this does have problems.
another thing is is my D2D version DID NOT auto patch itself so I was 1.0.5.
I had to manually go and run the gu.exe file that downloads the latest patch and installs it, people do not post what versions they have in which they're receiving these issues, so it's hard to tell if its from 105 or 115 if you get what i'm saying.
I'm using the latest version 1.1.5
the morning of March 2nd, I had reformated my PC to clean everything off the HDD for a fresh start, reseated the CPU heatsink with fresh thermal paste/grease. took my air compresser and blew all the dust out.
btw this is the lazy version of my spring cleaning, had I been in the mood I would of probly strip the PC apart and cleaned each part piece by peice hand cleaning the fans and heatsinks. and doing a systematic install of software Windows> latest Service Pack> Windows updates> latest Video & Sound Drivers> all other software> run disk cleaner & defrager> enjoy my 2 year old computer like it was brand new

and yes.. I have no girlfriend. and don't say I have no Life.. as I am a gamer, I have many lives....
