I purchased a youcam 4 upgrade two weeks ago and have not being able to install it on my laptop. I have contacted technical support 4 times now. They keep telling me to clean my registery and install the upgrade then. I have tried and tried and not succeeded. Everytime it comes to inputing the CD-Key it tells me that the key is wrong and to check the shipment order for the right Key. Technical support just sends the same message over and over. It takes them over three days to reply to my support ticket. I am Getting very frustrated with them messing me about. Can sombody please help me or if not how do I get a refund. They are not providing the service that they should by law. I am not paying more money for them to help. As far as I know this is against the law in my country. This is the message I keep getting from support. Which is of no help. Same one four times, I have tried and it does not work.
