I went through a lot of threads, but couldn't find anyone with the same problem: So I've got version 1.0 installed and after playing most of the campaigns & scenarios I downloaded a bunch of them to my pc. After unpacking them I copied the .btt & .cam files to their appropriate folders inside the Game Files folder. Some of them (for example A Disputed Village (btt) and A Bridge Too Close (cam)) show up and are playable, but the rest of them don't even show up in the Battle or Campaign menus. What am I missing and/or messing up? Is it because I haven't gotten around to download the patch for the newest version or the game and the scenarios are meant for that version or what? Thanks for the help and for a great forum!
