Draftsight for Windows (10) 64bit 2017 won't startup - crashes after activating

I just installed Draftsight for the first time, and after I start the app, it asks me to register.  I have tried this several times.  When I fill out the info, and hit activate, the program seems to start up for a split second then crashes.  No error message, it just goes away.  Any idea what can be happening?  I'm on Windows 10.

Thanks
