No joy. I renamed DEFAULT.RWS DXiPluginList.ini DXPluginList.ini RB.CFG RealBand.INI to have a ".old" extension and moved them into a new folder called "Old". That forced Real Band to recreate those files. I updated the build to 5, did the "Run as administrator" trick you cite, and it still isn't working.

From the Tracks window, I'm going to Ctrl.+F3:

I get the Import WAV file box:

Real Band now frozen.
