Contact PMDG Support directly for a ticket.This screen normally crops up if there is an issue with the validation.

but it didn't happen before just started now

Doesn't change the fact that it's a validation problem.

So should i reinstall the md11? If so do i uninstall the liveries first or the md 11 itself?

Hi Shayan, I wouldn't think it will make any difference if you reinstall it but to be on the safe side, the liveries 1st. So you don't need to go through lots of reinstalls later (or individual uninstallers again down the road for each livery), I would back up your aircraft folder. After you reinstall you can just plop in back in place and won't need to worry about the hassel later. Of course this doesn't fix your primary issue but there is no need to have registry links to liveries at all and running a livery installer will of course create strings in the registry for the uninstaller but other than that there is no need for it.I would try a repair first though, maybe you'll get lucky and that will be it. Other than that on a side note,,, did you recently move your installation? Just curious how this just started. My only guesses are either something got corrupt or moved.Good luck,

Thanks guys for the helpful advice. I reinstalled and It works now, however after several re-loading again it stops working but this time every thing is off nothing works and nothing is pressable...

This might be an admin issue with windows. I never install in the default Program Files (x86) folder because of the issues like this I often read. I would try again, but make sure you install with admin rights by right clicking the executable and choosing Run as Admin. It's also possible the FSX root folder doesn't have the proper rights and when whatever it is going on behind the scenes that the PMDG files write to for validation isn't being allowed to happen. That's the only thing I can think of, but not sure how that whole thing works. Most validation software writes something, somewhere. Sometimes it's impossible to find and if I did it to my own program would be written to my own unreadable code to prevent hacks, so again if the folders do not have rights, maybe that's it? The fact that you are just now seeing the issue could be because maybe you had UAC off before and something like a new group policy or security change happened and re-enabled it. Also make sure you aren't running anti virus crap when you install it and the first time you run it. Maybe your firewall is the culprit here and stopping a handshake from happening?Sorry but out of ideas on this one. If you don't get anywhere with the above, I would open that support ticket to the ones that know more about it.

I am running windows xp so i don't have the whole admin thing! Well i'll see what happens. Thanks for you contribution Dan, it has been most helpful.
