I recently bought the US PC Version, and am trying to patch to the most current version. What patches do I need to get, and can anyone help me with the location of them? I downloaded version 1.11.3 Full, but when I attempt to install it, it tells me I have the wrong version. I cannot find a previous patch and I don't have any mods..etc installed, so I'm not sure what I'm missing. Thanks much.
