Hi FD, long time no see.
First read
this, it's a step-by-step that Tarlanon wrote.
Second, make sure that all instances of "Program Files" in your config.txt are changed to "progra~1"
Third make sure that all instances of "progra~1\UAF" are changed to "progra~1\DungeonCraft".
One thing about the way DC works is that it stores two copies of the config.txt that are used in each design - the one used by all in the base directory, and the one specific for that design in the design folder. (There is actually another instance in the DefaultArt folder, but is only called if you have changed away from the 640x480 resolution and are changing back.)
If this doesn't get you good to go, please post again.
