[Blink] "Registration failed (No more routes to try)" error

[Kevin Layer]

I switched from Blink Lite to Blink Pro and now the same setup (user
and password) gives me a popup 

   Account xxxx
   Registration failed (No more routes to try)

I have two SIP accounts and I checked the passwords on both.  They're
both giving me the same thing.

Weirdly, Blink Pro works at work, connecting to the same server.

Ideas?  I'd really like to use the Pro version I just bought.

Thanks.

Kevin
