Hi im playing a Patrician 3 game with two friends, and it crashes a lot. We play using hamachi. We tried first deactivating autosave as suggested in some forum, and it seemed to work a little bit, but it is happening again. Sometimes randomly, and just now if I click on personal messages, it crashes instantly for me and sends me to the desktop.
I saw recommended to install the 1.13 version patch from fx interactive, but it doesnt recognize the game as installed, maybe cause I have the game from gog games. Is there any way to make it work?

This is one of the best games ever, it would be sad not being able to play it online. Thanks in advance.
