I have experienced a similar problem.... I just purchased the license last night and was unable to get the key code to work. The email that I received from P2Exe contained a file attachment which was only a text file. When i followed the instructions provided with the key code I got an error message that indicates the key is invalid. I would like to work on a presentation this weekend and have not received any responses from the tech support or admin email messages I sent. I'm feeling the same way..... was I ripped off? How long does it take for the tech support to respond?
