I think there is a procedure to activate your game via EMail (which you would have to access somehow - not necessarily on the same computer as GC2).

However, without internet access, the whole process of patching the game becomes a bit more complicated. You need administrator access to another computer in order to install SDC and download the patches so you can transfer them to you game computer.

It's possible, search through the forums, there are step-by-step instructions already there. But it's definitely not as comfortable as having internet access.

I believe you do have to activate the game game if its DA or TA, don't you? Could someone clarify the point for him?

Thanks for the clarification all, really appreciate it!
