FSFD3 causing MakeMDL to crash... help required

[Quixoticish]

I've been messing about in FSFD3. I've worked through the tutorials and compiled things properly, so today I thought I'd make a little virtual "stick man" make up of tubes and a big comedy head for a VA I'm involved with to use for viewing at airshows. However when I come to compile the model MakeMDL just bombs out with a visual C++ error. Other things compile fine and this has worked before. If I move some parts around it compiles, but then move them back and once again it won't compile. Then I'll move the parts around and again it won't compile. I've tried re-installing both MakeMDL and FSFD3, umpteen restarts, compiled lots of other things, I'm at my wits end. Is there some basic rule to do with FSFD3 that I could possible be missing? Has anyone experienced this problem before?

I'm sorry I can't be more specific but as MakeMDL is crashing I'm not getting any logs to post.

:sad:
