Hey guys, please try these steps and see if they help with this issue.
I too received the Snowshoe-67C3DC3A error. Funny thing is, I have finished the game and was playing coop Arcade with my buddy when it booted me out. Tried logging back in only to find that my save wouldn't load. Only option was "New Game." Not too happy about it. I submitted a ticket today, so we shall see what Ubi does.
I got this error driving the hot dog cart.. fired out my 2nd controller.. plugged in the Elite that got the error.. then took the battery out of the other one after getting around the error.. then it's good... but seriously strange error message .. BUT I'm almost thinking it has to do with the game sensing battery power? .. only saying that because it's been fine since i plugged it in to charge and kept playing
