how do i add more textures to my library in rf edit?

Since i set the game level to the one i built, every time i try to play the game and press done in the game menu with character selection on and off the game doesnt start and the only option left is "main" and when i click it it does nothing and i cant go back to the previous menu, whats the problem?

i tried building and running the final game but every time i run the final game it ends up being one of the demo levels. how do i fix this?

every time i try to cut in a door way between rooms there is always a top and bottom opening in the doorway i have cut, and when i try to compile the level i get an error saying that i failed to remove hidden leafs, i have the player setup and player start already setup, can some one explain to me ...
