Cheers mate, I will be working just on Overgrown now. I have started too many maps, and never really finished them. I'll have one, and I'll finish one now. Just like when I did The Swamp Trails, I have to commit.
I had a DLL issue before. tbb something. I put the 64bit tbb into the main folder. I can load up using the mod fine. I'd try a proper fresh install, folders and all when it asks for them to be located.
