Weird, it spreads between all 4 of my cores fairly evenly.
I was going to check it out for him, but aside from tying the serial code to my Uplay account, I can't even get the POS to load. First time it hung the computer and I needed Process Explorer to kill it. And now, it crashes to desktop immediately upon starting.
I'm seriously done with Ubi after this. I'm still going to pick up Rayman since it doesn't have DRM, but that's it. I liked their old garbage over uPlay. Uplay is the lowest form of DRM in my book. I feel like the Gym teacher in Seinfeld yelling "Can't Stand Ya!"
EDIT: Probably has to do with UBI not showing me as online. And my W7 network icon having a yellow exclamation warning sign. But that's a common W7 issue that is solved by fuck knows how. It comes and goes. So apparently this doesn't bother anyone but UBi. Pfft.
2nd EDIT: Just restarted windows and the exclamation mark is gone by my network settings. Go to start AC:B. Immediate crash. Restart a second time, it's hung at 27MB allocated to it in process explorer. Piece. Of. Shit.
