Whenever I try to download/install SS2.3 , an error window comes up and says that "install Launcher has encountered a problem and needs to close" When i close it, the Sonicstage Installer window appears but doesn't have anything in it. When I press OK, it says "SonicStage installer is currently running. Cannot upgrade SS2.3 while sonicstage installer is running. Close SS Installer and try again." What should I do? Idon't understand whats causing it? Help!
