So I tried to install the perkaholic mod and somehow in the process of moving the english_xml.pak file I accidentally ended up changing the default program for my .pak files to be notepad. When trying to load the game obviously nothing worked correctly. I realized what I had done and changed the default program to WinRar which didnt help either. Finally I tried dissociating my .pak file with a default program, and that still has not helped. Any help would be appreciated !!
