If we have misunderstood and you are trying to transfer your subscription, please let us know and confirm that AutoUpdate is disabled on your original computer (if it is still in your possession) or that SpywareBlaster has been uninstalled (if your original computer is no longer in your possession). Please let us know if you need instructions.
It sounds like with this quote that once you contact them and tell them what happened they will help you fix it. Have you looked over their forum and maybe make a post about your problem. Looking at a question that was posted much like yours in their forum should answer your question. Please post if they do, I'm interested myself how well they support the customer.
