and welcome to the forums. We will need a little more information from you in order to help.
What system are you using, spec wise, what platform are you using to sim on, any add-ons etc you are using etc? The more information the better we can help troubleshoot the issue you are having.
Basics to check are that you have run the latest A2A Updater;viewtopic.php?f=130&t=57819
And that your settings and sim platform meet the requirements in the manual, FSX updated etc.
