Hi there.  Strange problem.  My waves vst3 and vst2 plugs suddenly disappeared from the insert plugin menu.  I found the waves shell and directed sonar to the directory.  It scanned fine and the plugs are recognized and I can see them in the plug in manager.  They are also appearing in the menu layout in plugin manager.  Yet when I hit insert plug on a track , I dont see any waves  plugs.   Any help?

When you use the menu to insert a plug, check the plugin layout. Make sure that it is set to "default (all plugins)". Do they show up now?
