I had a 2.5 updated game on an external HDD, I had added 2 mods to the game, I could play the game and the mods worked ok. The HDD failed due to age, so I cleared my C drive and installed a new copy. Now when I try to load the game I get into the game all ok. but then I get informed that my authority has been rejected and I cannot play multiplayer, and I cannot add any of the mods that I have. Is it possible that something is in my register and interfering with my game.
