Tom, it seems your system reboot and clock reset have triggered one of the anti-clock tampering protections built into Shozam. Our Development Team is working on a fix so you are not left stranded. This is related to the larger issue of key activation and protection which is causing the release date to slip beyond the scheduled release date. We have a dependency on a third party for this functionality and we are in turn frustrated with the delays.
The purpose of the Beta program is mainly to identify any major issues, like the one you experienced, and ensure these get fixed before we offer the program for sale. In any case, rest assured that if resolving these issues triggers further delays, we will keep extending the Beta program so early adopters, like you, are kept with an operational program until the actual release date.
We are working around the clock and doing our best to quickly fix any of the remaining issues. Additionally, we had our Design Team work on refining the release version of themes, increasing their number from 8 to 20 and providing them to the Beta users (the final themes were originally scheduled to be offered only in the retail release version). I hope these offerings will help alleviate some of the frustrations that are inherent in adopting a program during the Beta phase.
