My FSDT airports are gone

[looping]

Hi,

I've purchased some time ago CYVR, KLAS, KLAX, KORD, KDFW and LSGG.
They are gone, I don't know since when, all buildings missing.
Their scenery folder are nearly empty.

How can this happen?

This is somehow FRIGHTENING!!

What do you suggest to get them back and, above all how can this be avoided?

Awaiting your suggestion.

Hi,

I need to add that all these airports are listed as functional in the FSAddon manager, however they are not.
Should I reinstall?
What is best procedure?

Looking forward to any helpful response.

Thanks
Ernst

The usual question:

Do you have BOTH the "Addon Manager" AND the "Couatl powered products" under the FSX "Addons" menu ?
