Program used to work fine, now it will not activate

I recently tried to use the program for the first time in a while and when i booted it, it asked me to reactivate. I tried a few times and it never worked, so I uninstalled the program, downloaded the newest version, installed that and still had the same issue

When I first start the program it boots as normal, then this box would pop up:

I clicked "Activate Now" and got this box:

I filled in all that info, clicked reactivate, and i get this:

If i just click ok the program completely shuts down, if I check "Edit DraftSight Proxy Settings" then this appears

I haven't tried messing with any of those proxy settings, our IT group can be pretty strict with those type of things so i generally avoid it, the program used to work just fine without any proxy info anyway, nothing has changed at all. Any ideas?

Thanks!
