Topband: DX Summit connection problems

[Herb Schoenbohm]

I use DX-Summit at times to monitor topand activity.  But for some 
reason the connection is rejected via my normal ISP.  However when I use 
by Android on ATT there is no problem connection.  The same ability to 
connect is via another computer hooked to a different IP address.  One 
local ISP is blocked and the other isn't.  I just hope someone can help 
me with this as there must be some simple solution.  On the DX Summit 
site I can not find a "help" or "contact" person to send my problem to.

Thanks,
