I read in another thread in General that the patch would not interfere with save games, however, that keeps popping up whenever I try load it. This goes for the individual save file, and the autosaves.
I literally downloaded the new installer, and ran it, same installation directory on the same drive.
I honestly don't remember, think I updated to 1.5.4 but.. may not have.
Thanks for the offer but I have decided to just restart, I had been having ideas of things I wanted to try differently, yet couldn't bring myself to abandon the current game. Now I have a "valid" excuse :)
