Well, I just realized that I've played the game a bunch of times at version 1.0. Tried the windows listed for patch download but I am not sure if the EU patch would work with my version (bought in the USA). I also just bought the expansion pack so I know I at least need 1.3 and that 1.2 supersedes 1.1 so the question is, do I need 1.2 or just 1.3 (1.3 allows compatibility with the expansion pack). Alternately, I seem to remember that I can provide "Steam" with my CD key and have access to the latest patched version but I could not figure out how to do this. So, what patches and where to get them or how to get them from "Steam" seems to be my questions.
