These are new saves, made earlier in the day, and attempted to load later.
Playing on Win10 [same machine as I played it on last year, when I had no trouble].
Purchased thru Steam, so there aren't any files to speak of on my machine. I uninstalled using Steam's uninstall function.
Warlock doesn't show up as being installed on my machine -- altho some Steam games do -- so I cannot add it to an exceptions list. However, I am able to start as many NEW games as I like, so it doesn't seem like the anti-virus is blocking the program per se. However, when I start the game, go to "Single Player," click "Load," select a saved game from the list, and then click "Load," I receive this message: "Save game loading error: file does not exist."
