I di the same and when it launches got a message that the trial version woudl only 5 minutes of DVD, and prompting me to register.
When I uninstalled it, a web link was launched asking if I wanted to pay half-price in return for advertising it on my twatter page, or feacebook.
After declining to pay half price for somethign that was advertised as no-strings-attached-free I was then prompted to send an email to explain why I had uninstalled the product.
I took that option and told them that I was removing it because if the wording of the offer was being broken; I had no confidence that the product itself would function as they claimed either. I received a reply overnighjt apologising for the web link being incorrect, and with a new direct link the (correct, free) download. It downloaded and runs without problems, no registration required. Kudos to them
Unfortunately, here at work I am not allowed to get at my own email, so can't post the link ....:-(
