So I assume you tried reinstalling your server and it does still show the RMS server. That should mean your server does not use the data folder for connection but still reads the data folder. In that case, yea delete the data folder then reinstall your server client. Or go into the data folder and delete the clientinfo.xml that is the only thing that will show you the RMS test server. I feel bad you have to uninstall everything, you shouldn't have to.
