You already sent this by email, and I already replied to you but, because of an error in your email configuration in your system, my reply bounced back with an error that your mailbox is unavailable so, it's good you wrote on the forum, but please check your email config...
In any case, this is the copy of the email I sent to you:
The prompt is not telling you to buy the GSX Level 2 expansion "so that GSX would work". That's not what the message said.
The message said you should buy the Level 2 expansion to OPERATE the NEW jetways. GSX never controlled jetways before, it's something that has been added to the Level 2 expansion so, the "old" GSX will continue to operate exactly as it was, without being able to control jetways, as it always was.
Installing the latest GSX has of course enabled the Level 2 expansion in TRIAL, which means:
- It has replaced all old default jetways with the new ones, which are much better, and work better.
- As long as the Level 2 expansion is in Trial, the new jetways will only work on Trial airports. If you purchase the Level 2 expansion, they will work everywhere.
- If you are not interested in having much better jetways everywhere in the world, and want to go back to the old default jetways, as explained on Page 4 of the GSX manual, you can just use the GSX Control Panel utility to restore the default jetways.
