Ok, thanks, but what do I do next? The VstPlugIns dir is in place in the Logic5 dir, but logic still dosn't start but freezes on ! "Initializing external sample editor communication" . So what is logic doing there - somthing to do with log_ds.ax? And where does that file come from? It dosn't appear when I reinstall logic ( update 5.5.1. or 5.3) but it didn't appear. Tried a file from a friend, but it doesn't work. Ole
