I downloaded & installed the new v1.44 Beta (with the "New activation and trial mechanism") on my own machine, and it prompted me to re-enter my product key to activate. No problem.
My concern is this: I'm a computer consultant and over the last 18 months or so, I've purchased several dozen separate Start8 licenses (under my own account) and installed them on various clients' systems. I'm worried that once this beta hits general release, I'm going to have to walk several dozen non-computer-savvy clients through the process of re-entering their Start8 product keys. Yikes. This could mean a LOT of unnecessary service calls on my part.
Please tell me that before this beta goes into general release you're going to change the installation routine so that it doesn't require re-entering the existing product key!
