On 3 June, I opened a ticket (33C-139B2E69-9BB0) in which I describe a JS41 reactivation problem. I don't recall the exact error but the gist of it was that activation is denied due to too many installations. The next day (4 June) Paul Gollnick replied to the effect that "The installer file explicitly outlines the limits of installing the product on Two Computers per license". He then went on to say that he had forwarded the matter to Robert who would likely review my installation history before deciding whether I'd ever be allowed to install again.I replied to Paul that I do not ... have never ... and will never ... install on more than one machine at a time. I then went on to explain that, when I first purchased the JS41 in December 2009, I installed it on an iMac which was dual-booting Windows XP specifically for FSX. The iMac died earlier this year and I built a new i5-750 based PC (Win 7 64-bit this time) onto which FSX and the JS41 was installed. The original FSX/JS41 installation on the iMac were wiped out so again, the JS41 was installed on only one machine. Since building the new i5-750 box, I've reconfigured it several times ... adding whole bunch of memory, new disks (notably a 600 GB WD Velociraptor for FSX), reallocating old disks (two 160 GB and one 750 GB Seagate Barracudas) in order to try various implementations of Linux and/or Win7-64. Recently, I pretty much got tired of experimenting, wiped everything but the 750GB storage disk, and reinstalled a pristine Win7-64 and FSX environment. All went well until something apparently tripped the "too many installations" alarm at PMDG and I opened the aforementioned ticket.Since then ... silence. No activity on the ticket ... no further response from Support ... and no response at all from Robert.So, Robert ... if you read this, would you either review my installation history and decide to allow me to install an otherwise excellent aircraft ... or at least authorize someone to handle it if you are too busy to do so yourself?Thanks,Mike

If it hasn't been dealt with, there's a good reason for that. The system is very specific about it being installed on multiple machines, simple changes of HDs and OSes will not trigger this response. I'm sorry, but I believe you're out of luck unless you purchase the aircraft again.
