I recently had some computer issues and had to start from scratch. I copied my main drive to a secondary drive so I wouldn't lose any information, unfortunately the move did not work and all I could find was empty file folders (Thanks Bill Gates). I had to re-install AHP from scratch and had no issues with registration or the software running properly, I did have to install the update separately though. I had printed out the e-mail with my registration code and had the AHP install on a cd-rom. The only downside to this type of setup is that you lose everything. I am currently adding all my modules, timers, and macros. The cm-15 worked just fine without AHP and all of my timers and macros worked without issue, until I added the AHP software and it reset all the settings for the cm-15.
