OK...tests with XA regarding distribution and DRM done successfully. I have to say, this system is fantastic without being obtrusive. Kudos to Cam and BenR for providing a professional installation and management experience.....I mean, just keep your XA user and pass handy and you should have no issues; HOWEVER, that being said, I think this is the first 64-bit gizmo product to be distributed and though we have endeavored to cover as much as possible based on past experiences, this will be a new "trial" on a mass scale. This MU2 1.5 update will be for V10 only and 64-bit only. The "x-plane consortium", consisting of laminar and lots of devs all agree that 64-bit is the focus and future and we need to leave 32-bit behind...that's just the way of computer technology. My computer is old and ratty and 64 bit works great for me. So....this SHOULD be out during the weekend (assuming no "non-flight sim" related life surprises or emergency reshuffling of priorities). This is not a promise but rather an 'educated estimate' based on my years of troubleshooting and knowing when and what causes delays and issues, at least when close enough to see the finish line (far away estimates are always cloudy). I have tested the MU2 rather thorougly and its performing very reliably on my machine, but my machine isn't your machine so we'll see how it goes. So what is happening now is I am going over the what's new docs, preparing a impromptu video showing the new features and basically cleaning up the package, dumping old legacy files. I am NOT working on the code or flight modeling...that is all done to my satisfaction and now the DRM and activation tests are complete also. This MU2 is head and shoulders above the "old experience" and sadly, the last free major update of the version 1 run. (minor bug fixes will still be performed if needed) Tom K
