I also just purchased this product via Paypal. Although I have the receipt, there was no automated email with registration details. I sent an email to firstname.lastname@example.org, as the form on the sles support page will not go through. It says "Server cannot process your request. Please try again later". How convenient.
The "Continue" button in the final Paypal dialogue box wouldn't open any web pages. Moreover, there is nowhere to actually download the trial version either! I bought the software on trust (on the basis of the screen shots) and now I am utterly demoralised.
There is no phone number to talk to a human being. I feel like I've been ripped off by an online scam.
Could you please give me the details to register. Once I receive a reply on this forum, with a monitored email address, I will send my email with a copy of the Paypal receipt. I note that the only thing that happened flawlessly was the debiting of my credit card (I checked with my online banking site).
