Tried to download Allen Thompson’s new one shot wonders campaign, the download worked just fine, but when it said installing, I got this error aobut4 seconds after it said “installing”. The map pack seems to work just fine when I played it, and the new changes were in effect. --------------------------- --------------------------- An error has occurred.
