So now that Ion Fury has released, the download has changed to the full version. But it doesn't appear to contain the Preview Campaign content, and there are no bonus downloads yet, which means that the only Preview Campaign version available is that from the free demo - Preview Campaign Update 2 (20072). This is an earlier release of the Preview Campaign, however, so will we be able to get the latest version back - Preview Campaign Update 4.1 (26967)?

In the full version, the preview campaign is available from New Game -> Bonus Missions

Wow, I completely missed that. I was looking for "Preview Campaign" instead of "Crisis In Columbia". Thanks for pointing that out. I can relax now. :)

Just FYI, with GOG Galaxy you can always go back to at least the last few versions of any game by going to game settings -> Installation -> uncheck "Automatically update to newest version", then choose a past version.

(I forget the exact names of things in Galaxy 1.0 because I'm using Galaxy 2.0, but it's there.)
