It is caused by either one of these two things:Hi @Toffer90 , I installed c2c v39, tested it and it run fine. When I installed PPIO v0.7, first deleting UserSettings folder like you advise, I get an error when I load the mode, saying GFC error failed to initialize primary control theme (or something). The same thing occured when I previously installed the latest SVN build (10781), also tried SVN 10777, but when this happened only after installing PPIO on v39 I though it had to do with this modmod.
1. The name of the folder that the mod is in must be exactly "Caveman2Cosmos", this was a rule before PPIO too as it caused instability to name it something else, PPIO on the other hand demands the name to be correct.
2. If you have the mod in "...\Documents\My Games\Beyond the Sword\MODS\Caveman2Cosmos", even if you name that last folder correctly.
The mod must be placed in the folder where beyond the sword is installed on your system.
Should be something like: "...\Sid Meier's Civilization IV Beyond the Sword\Beyond the Sword\Mods\Caveman2Cosmos"
