What Is wrong with my SRB2 Doom Builder?

[csmgiw]

When I add a FOF to my up and comming supersonic race track, and try to test it. But when ever I do as it is pre-adding the file to the game it will say Error #6 storemaplumps in a message and the game won't come up.
I have used FOF's before to stop my friends from beating me in levels, (Mean but funny) So why is the program now acting up?




Note: I hope my grammer is correct. Is it?

Do you have vertices outside the red boundary?

 

[csmgiw]

Not at all. Though if that were the case I might not have posted this

I asked because that's the most common cause of that error. I think I've also seen it occur due to node-building problems. Do the nodes build correctly (you can test using the button on the toolbar)?
