I believe the patch needs the cd but maybe wrong...its quite possible u have a corrupt patch, or perhaps ds2 didn't install right. may have to uninstall ds2. reinstall it, the see if ds2 runs as 2.0 then try to patch again with a fresh download from - http://download.cnet.com/Dungeon-Siege-II-v2-2-patch/3000-7536_4-10442335.html and try again... and yes keep antivirus off during patch. I assume u aren't using the steam versions.
