it's not so much technical difficulties, more of downloading all ~4 gigs for crysis, then all 3 gigs of the mod (hell of a mod when it's almost as large as the source game), dropping into a normal cyrsis game,then getting my CD key saved correctly, then reducing the many CTDs I've been getting. It's almost enough to get me to go out and buy seven 64 bit, lol.
I look forward to getting some solid time in.
