I've got the gold edition of DL/DA on cd (I think version 1.5?).  I just got the new expansion cd delivered here to my office.  Does the new expansion cd include the updates for DL/DA?  Or do I need to download patches as well?  I need to know because I don't have internet at home right now and anything I need to download I have to do it here before I go home.

If I do need to download updates, how do I do that?  I have stardock central on my office computer, but not the game.  Can I just get the update from the gold version without downloading the whole game? 

Thanks.
