We you send private messages AND post the same message on the forum ? Since I've already replied to you via PM, what makes you think you are not being answered ?
As I've already replied via PM, it's obviously not possible to help you with such generic report. What do you mean with "not running" ? Have you pressed the GSX key on a supported airport ? What happens ?
Do you have both the Addon Manager and the Couatl menus under the Addons menu ? If yes, have you changed the GSX hotkey ?
Are you running IVAP ? That uses the same hotkey as GSX (CTRL+F12) so, you need to redefine the GSX hotkey to a different one.
