Map2Dif - error?

I can't seem to get QuArK to export my interior, the following error occurs:

Creating BSP...::createBaseWinding: Bad face on brush. < 3 points. DMMNOTE:
Handle better?
::createBaseWinding: Bad face on brush. < 3 points. DMMNOTE: Handle better?

.... Has anyone come acros this before? if so what was the solution?

Many Thanks,
