There's a dedicated support area for the Airbus Extended, so I moved this there for you. The General section where you first posted is for products without their own dedicated section.
You didn't mention whether or not you use FSUIPC, so I guessed you don't. If you do, simply reply back and I'll move this over to the FSUIPC support side. Also, now that you're in the right support area, please take a look at the threads with related titles and follow the troubleshooting posted.
