Hello there. I've tried both the upgrade patch version and the stand alone version and I keep getting the same problem. When using the Final Frontier Plus shortcut I get the following error: "Mods\Final Frontier Plus \ is an invalid mod directory, ignoring" I checked and the folder is there. It has stuff inside that resembles that in the regular FF directory. When I launch BTS and look into the mod menu FF is there, but FFP is not.
