I have a similar issue with my CP-4900. I followed the instructions for the installation of Galaxie v1.9 and the GC controller. I am able to setup and connect the system via the Configuration Manager. The CP-4900 communicates and sends/receives the settings. Note that the two channels/columns are colored red, everything seems ok and the CP-4900 is Ready. I do not if this ok and indicates an issue.
When I open the Galaxie software the system does not appear at all, for any user. I have only one system so I do know if it is a problem with the CP-4900 or the Galaxie.
Does anyone have any idea about what can be the issue? I am completely newbie on the matter.
Forgot to mention, that I also tried with the local distributors (I am based in Qatar) with no luck. They stopped trying way earlier than I reaced.
