I installed DraftSight 2015 SP3 x64, no problems during install.

Then for activation, I set proxy settings, then I type in Email, and receive an email. So far so good.

I click on the link in the Email and it sends me to a page that says activation was successful.

Now the problems begin, I start DraftSight, it tells me that I need to click the link in the Email (I already did), or specify a different mail address. When I click to continue, DraftSight crashes, I get a generic Windows box that says "DraftSight has stopped working..."
