We found some crashing problems in PCM 0.5 related to the Gothic civ. Since the fix was small, we decided to not release an installer, but, instead, release a hotfix. So, in order to download the hotfix, just click here.
To install it, just replace the .dat which is inside C:(Path to your AoKTC folder)GamesPortuguese CivData folder.
