SW crashes when inserting BOM?

I have a drawing that was working fine. I reworked theassemblymodel some and when trying to re-open the drawing SW justwent awaywithout any warnings or messages.  I spent the betterpart ofyesterday re-building the drawing from scratch and when Iwent toinsert the BOM, SW #\$%&@*& crashed but left behindthefollowing error.

 

Runtime Error!

 

Program: C:\Program Files\SolidWorks\alsworks.exe

R6025

-pure virtual function call

 

So I assuming there is something in the assembly model BOMthatis causing this problem? But I don't know where to beginlooking? Ihave tried doing a save as on the drawing and usingdifferent BOMtemplates to no avail.

 

Any suggestions?

 

Thanks Rick
