For anyone else wondering about "Goback" it was sold by Roxio to Symantec years ago, given one brief update and then consigned to the warehouse of products bought by Symantec and then allowed to die - it is no longer sold. For any that have the last release from Symantec (like me), it still works just great on older single processor systems. It has issues on multiprocessor systems (though I discovered that running on this dual processor system with asymmetric memory the problems go away) it must be considered for the future, to all intents and purposes, a defunct product.
