Skipper, it would appear that I too have been scammed by DVDunlocks4u.:sad:
I've now sent them a total of 7 messages asking for help on getting the files that they've sent me to work. I only get evasive replies such as "What is your Paypal Id" (even though it was on my email).
I'd sure like to hear from anyone that has come accross an unlocking fix that actually works.
