Map2dif plus crash since constructor 1.02 upgrade

Last night I upgraded from constructor 1.0 to 1.02, installed into the same directory as 1.0

my current interior now fails to export, file->export->edit export-> test gives the following before the crash

  Creating BSP...

I have not used any triggers in the map.

I have created a hollow cube and exported it with no problems

I have deleted constructor and reinstalled version 1.00 and the export works fine... I can provide the map file on request if needed.
