Before you export ALWAYS use the preview function in the exporter. If it previews fine then you will always have a backup copy of the B3D file in your 'plugins' folder named 'temp.b3d'. Just rename the file and copy it to where ever you want it to be.
The exporter crashes very often for me but a preview always works and so it makes little difference in the end.
