I bought Registry Reviver and was given a activation code which is INVALID! I have written them several times and always receive the same reply: You code is valid - make sure you hatrive the latest version. I've uninstalled it and reinstalled it again. Still nothing. This company is nothing but a scam. They won't refund my money, and they won't give me a new code. They say they have tried it and it works! This is NOT true. Stay away from this company and DO NOT BUY any of the products!! Then you won't have hours and hours of frustration!
