My DXi have all disappearred!!

Recently I tried organizing my plugins in the Cakewalk adapter by going into their Properties and typing reference names(i.e. "Krakli" before my Krakli VSTi, "nOVAKILL" before my Bones VSTi, etc.). Well, I noticed yesterday that all the Shared DXi that come with Sonar are gone from the Synth Rack! Will the Synth rack only hold so many instruments? If I bring up old projects the Revalver still appears, but there's no way to bring it into a new project.
One solution is to use the adapter that came with Magix Music Studio to yank a lot of the plug-ins away from Sonar. Then I can see my DXi. But when I load them all back in again the DXi are gone again. What do I do, remove the reference names from the synths and go back to anarchy? I just wanted to organize a little!

Well this oughtta show everybody what a super-genius I am: I threw on the Sonar install CD and discovered that, even though I've had Sonar for over a year and made a whole album on it I'd never installed the Plugin Manager. Not only that but all the MusicLab MIDIFX, the Style Enhancer and the Audio Finder were not yet installed! Brilliant me. So I brought up the Plugin Mgr and there they are, all my DXi on the right-hand side with the other plugins, looks like they should be fine, but they're still not showing up. What I want is a "make this plugin appear in the Synth Rack" button, but I'm not seeing it. Maybe one of these free synths I've downloaded is gumming up the works somehow. Dunno.
