After upgrade to 2017SP1, Draftsight crashes after entering activation info

I downloaded Draftsight SP1 2017.

Then I clicked on Draftsight icon

It says it needs my email, occupation etc on Activation page.

After entering this info and clicking ACTIVATE it sits for about 1 minute

then crashes!!!!!!!!!!!!!!

 

p.s. after several attempts I notice that memory use climbs to about 1.8GB

on a 32 bit machine.

 

This software is now unsuable!
