There are two distinct versions of the SDR-Radio.com servers. You must select the correct version for the software you are using. Follow the advice below and enjoy remote operation.
Version was was unsurprisingly the first version of the SDR-Radio.com software. Development has stopped but there are many users of Version 1.

This is the recommended version folks!
