In regards to My Traffic 2010, if you have installed traffic bgl files that were made with FS9 traffic tools this can cause My Traffic 2010 AI to not show up.
The first thing that I would do is to uninstalled MT2010, reboot, start FSX, quit FSX, reboot, deactive any and all traffic bgl's that you have loaded, start FSX, quit FSX, reboot, install MT2010, reboot, start FSX and see if you have AI. If you do and you want some of your previous traffic bgl's then you are going to have to activate them in some kind of logical order until you find the one or ones that are causing your MT2010 AI to mess up. Traffic bgl's that were made with FSX tools should be okay, the problem is traffic bgl's that were made with FS9 tools and earlier.
MT2010 is sold by Aerosoft and Aerosoft is suppose to provide support and they should have a support forum. With that said below is a link to the SimFlight MTX forum that is ran by the author of MTX, MT2010 is by the same author, just that it is sold by Aerosoft. You can read the stickys on this forum in regards to your problem along with other threads regarding the same problem and download the free tools that can help you find all of your traffic bgl's that you have installed.
