I must have to say that you have the worst licensing process I have seen in my whole life. I don't think that ever with any other software in my 20 odd years with IT I have experienced such frustration. 

Moreover when I got fed up trying to run the demo, I wanted to uninstall the demo software - there is no uninstall option. I just can't resist swearing and using bad words just out of frustration. I seriously have never seen such a stupid system of licensing ever in my life, which doesn't let you run the demo - the only reason why demo was created is made redundant. and no uninstall option, this can't get any better then this..
