First: I deeply appreciate all the work you modders have put in to create and improve Caveman2Cosmos, it has already given me years of pleasure playing this game now. Just recently, I upgraded to v39 from v38.5 and I also downloaded the Interface Overhaul modmod. And while it works, it doesn't work properly. I cannot open the CivicsAdvisor screen anymore (and F3 only lets me adjust the sound, not open the Civics window) and I keep getting these eventmanager errors. While I already searched for help here and discovered that it has something to do with Python, for the life of me I can't understand what exactly I need to do to fix the problem. I don't use Tortoise so I can't use that program to clean up the folder, as I apparently should, nor do I use the SVN version. I don't know anything about programming myself. What should I do to get my game properly running again? The messages I see keep showing me this, for example: 15:24:38 TRACE: Error in Init event handler <bound method BugEventManager.onInit of <BugEventManager.BugEventManager instance at 0x0DFD9FA8>> 15:24:38 TRACE: [Errno 13] Permission denied: "C:\\Program Files (x86)\\2K Games\\Firaxis Games\\Sid Meier's Civilization 4 Complete\\Beyond the Sword\\Mods\\Caveman2Cosmos\\UserSettings" The latter seems weird because, according to the thread for InterfaceOverhaul, I should delete UserSettings and I did, but now the game seems to want to use a non-existent folder anyway. I have uploaded the log file in the attachment. Major thanks if this can be fixed, I would love to keep playing this amazing mod.
