There is a reference to GSA on the multiplayer page, and a GSA logo is displayed on the D2 login screen. A GSA login is required for the D2 but is not explicitly explained on that screen. Conceivably one could get a GSA login without thinking of checking the OP lobby, and therefore missing the updates. GSA is the only entity referred to in the original documentation that is still running I think. And without referring to a site that has the update to the ini file for the campaign server the D2 is out of reach. After doing a few searches I did end up with the patches up to 2.5.5.2 but a lot of the patch links did not go that far and also a link to GSA. I found no links to this site or to StarFleet Universe at the top of the search lists, so I think it would be a lucky person who got a hold of a copy of SFC:OP and ended up here. Unfortunately I don't think anything can be done about this.
