Hopefully I've placed my query in the correct place...
But. I'm having issues playing a game on NWN 1. The builder is using Diamond version patched to 1.69 NO CEP. And as far as I know, no other packs. I have the retail version with HotU and SOU. As well as CEP to 2.3. I shouldn't have any trouble playing something that was built using Diamond versus my game. Should I??
