Purchased for $235 an unlimited license from DVDFAB.CN. Installed the copy program on a dozen of my computers, both desktops and laptops. As computers improved CPU speed and sophistication, my hardware improvements followed. Over the past 10 years my hardware has accumulated and from time to time, I have used parts from older machines and have thrown out some really slow and out of date machines. Usually I have a half dozen laptops and a half dozen desktops. My DVDFAB licensed software is never shared with anyone. Early on, I never had trouble with putting the program on my computers, but recently I keep getting the message that my machines are not authorized and that I need to restrict myself to one computer usage. That is not what I paid for. I have notified DVDFAB.CN at least a dozen times that they need to honor my multiple license purchase and all thsy do is ignore me. So "BUYER BEWRE" this organization is dishonest. They do not respond to customer concerns. Lately I have asked for my money back and they have ignored that request as well. I will do everything that I can to broadcast my disappointment with DVDFAB.CN poor experience. My name is Ronald Getz and my email address is rongetz@wowway.com. I have my receipt to prove my end of the transaction.
