GSX Problem pushback

[Donato]

Recently, GSX has a little problem: I  do not see the pushback tractor that pushes the plane. I think the problem is probably is since I installed the last update. For the rest it is a wonderful FSX addon.
Can you help me?

You probably updated GSX just with Live Update, but forgot to update the vehicles too. Either download and install one of the vehicle updates, or download and install the latest version of the Full installer.

Now I try reinstalla the complete GSX program.
Many thanks.
