The internet connection in my area is very sporadic. If connection to GOG Galaxy drops out, the game menu tells me as much, but it also prevents me from playing the campaign. I can get to the screen where you have two big buttons to pick which campaign: Marines or Cranioids. Whichever one I click, it just opens my web browser on the page to buy the Guardians DLC. Does anyone else have this problem?
I'd really like to be able to continue playing the campaign.
