I got a weird issue, after I installed KIAH by using the download link all my other FSDT scenerys are deactivated and when I click register serials and type in my key, nothing happens (just return to the scenario, no conformation or fault message).
For the scenerys the Addon manager says they were installed, but in Trial-mode, for GSX it only says Trial-mode. I already run the Live-update installer but without success.
