When playing RFC world builder crashes my game.

When I try to use the world builder the game stops working and simply asks me to close it. This is in BTS, if I just play BTS without loading RFC WB works fine.

Nevermind people, I do not know what worked. But, after reinstalling it for the 4th time and again downloading the most recent RFC again It finally works... not clue wth was going on but, BTS 3.19 RFC can load world builder.
