It should be obvious by now that the problem is with the Addon Manager and or Esellerate. There are no other alternatives, not now after all I have done.
What you wrote prove exactly the opposite:
Then re downloaded FSDT KLAX and installed it. Started FS and it crashed/quit.
Re started FS as Admin and it started.
This seems to indicate the cause was neither the Addon Manager or Esellerate, but it was a PERMISSION problem: it shouldn't be normally necessary to have to run FS9 as Administrator but, fact that you had to do and IT WORKED, it means there's something wrong without permissions.
Using the Addon Manager within FS, I reinstalled (again) the product manually as the "Esellerate site" failed.
So, you HAVE been able to use the Addon Manager, which clearly proves the Addon Manager WORKS on your system. There's no such message as "Esellerate site failed". Please indicate the exact text of the message, because this might be an *entirely* different issue, possibly caused by an external product such as a firewall which prevented the Esellerate activation server to be contacted. In fact, you said yourself the manuall offline activation WORKED.
Exited FS and tried to restart it, again without success and with it crashing/quitting.
No matter what I do, as soon as I install FSDT scenery, FS crashes/quits and FSDT scenery, or those things associated with it addon manager, is the only scenery that causes issues with FS not starting. I even tried starting FS in both Full Screen and Windows Mode without any success.
No, this is not what happened, according to your description.
What happens, according to your description, is NOT that "as soon as I install FSDT scenery, FS crashes/quits" but, instead, it seems that there's no crash if you run FS9 as Administator, there is a problem reaching the activation server, you ARE able to manually activate, but if you exit from FS9, enter it again, it will quit on that 2nd restart. This is what you wrote: have I understood it correctly ?
At the moment, and considering I have done everything that you have said to do, and if (as said in your last post) there are no other options then the only thing that is left to do is to refund me my money as the scenery is not usable on my system, regardless of what the Trial says.
Because of the availability of a Trial version, we don't have any refund policy.
But that's not the point. The point is, you bought those sceneries YEARS ago, some in 2010, some in 2011, you just can't aks for a refund now, when you obviously used it successfully for years, it's fairly obvious they work, you reinstalled them several times, you reactivated them several times along the years so, obviously, what is preventing them to work NOW should be something else that has changed in your system configuration.
I've checked some of your orders, and several of them had reached their maximum available activations, so I've added activations to all of them.
If it's ok for you, we can arrange a Teamviewer session, so I could have a look at your system. Download the free client here:
http://www.teamviewer.com/Then contact me with a PM during working hours (CET time) when you are ready to start a session with the ID and password.
The real question is: with such a very good system, WHY you use FS9 ?? That doesn't have anything to do with your problems, we WILL have the sceneries working but, are you aware that your system is ENTIRELY WASTED with FS9 ?
