Hello there!

I am having some issues regarding the draw and design of a curstom part. In this case I draw in AutoCAD a block with all the information that I neeed of the part. Proceed to import it in Solidworks Electrical in the Symbol Managemente option. After that i generate a new manufacturer part through the manufacturer part management. When i finish i try to link both but the electrical connections do not appear. I try to update the symbol and the software crush.What is happening?

This is the symbol

This is the error that appears 

And finally the -dmp file
