If I had selected yes to open the error, do you really think we'd be having this back and forth...
Are you saying the error log showed once, and then never again ? Because, if it's still happening now, the only thing you had to do, was just start the sim again, to look at that screen. If the error, instead, is not happening anymore, then why bother posting about it ?
why the hell can't you make this easy and tell me where the error log is stored!?
For the obvious reason I assumed the error keep coming at each startup of the simulator so, it should have been obvious to you as well that it would havbe been enough to start the simulator again, and get another chance to say yes to that message.

That error indicates you haven't run the FSDT Live Update or, as usual, an antivirus/firewall might have prevented the Live Update to do its job or, you installed the OLD version of JFK2 OVER GSX Level 2, because that error clearly indicates you are running an old version of the JFK2 code, one that belongs to the previous version, and not the one which is currently online now on the Live Update server, which is not possible NOT to get it, unless something else is interfering.
So, again, running the FSDT Live Update now, will surely download the latest JFK2 code, because the old one you are running it's just not online anymore.
