Having had this game since Xmas, I have only just got around to installing. What a complete pain in the arse!! I couldn't believe the trouble I had to go through to get it to work. I've still got crappy 56K modem. After several attempts, in all it took 3 hours of fiddling about before it would finally work. The key to making it work offline I found, was blocking it in XP firewall. Anyway, I'm sure it'll be worth it. The point of my thread is that shortly I will be able to finally get broadband where I live. When it finally arrives, I am planning on a complete re-format of the hard drive to remove unwanted rubbish & address various issues that I have discovered since the first install of XP2. I have obviously created a steam account to make this damn game work, but will I be able to re-install?? My understanding is that the CD key is linked to the account. I also read this must be accessed at least once a month to keep it open?? I assume if I don't & try a fresh install I could run into problems.
