Okay, so I bought Dead Rising 2 yesterday for my computer, but I have encountered two (minor-ish) problems:

1. My gaming computer isn't connected to the internet, and the game wants to register (or something along those lines) with Windows Live. Do I have to lug my gaming computer monolith tower to my modem and do as the game demands? (Will this even work?) Or is there a way around this?
2. Once I've gotten past the first step, do I constantly need to be connected to the internet whilst playing the game? (It's not a purchase through Steam)

Any help ASAP would be appreciated
