Sony movie studio 13.0 about a year or 2 ago cloned itself within the application's folder causing 2 instances to open with every launch . When I uninstalled the clone it is forcing me to register the software again though unfortunately I can not find the box for the software with the item serial number to do the registration . is there a reason that the software requires a registration and is there a way to regain access to the software since it was already registered ?
