Your copy of bglmanx.dll is outdated. Please install the newest version of Addon Manager.
It's not possible you would see this message only with a certain airplane.
This message only happens if you installed an old version of the Addon Manager (like copying the .dll from an old installation, manually), or if you had a problem with the FSDT Live Updater, and SOME files were updated, and some weren't. This is possible if your antivirus or firewall blocked the update of SOME files, but let it pass others, resulting in a mix-up of new/old files, which is the only reason for that message.
But, if this what is really happening (not all files were updated), it should happen with each and every airplane. The code which gives you that message, has no knowledge of the airplane used, nor it's related in any way to the loaded airplane.
Are you SURE other airplanes works normally, with GSX and all ?
