Thanks for the reply. They already sent me the new keys starting with A. But when I try to activate them, it forces me to use the ones that start with FSDT. I've uninstalled everything, even deleting the registry, and when I reinstall it, it won't let me activate it with the new keys. I get a message saying it could be the firewall, the web communication, or that I should include it in the antivirus exclusions. I've done everything it says, but nothing works. I've realized the problem is when I install any FSDT product, and when it updates, it seems to change a file, rendering it unusable. I really appreciate your expertise in helping me solve this. It's really frustrating because I have many FSDT products, and after the last update, I can't use them.
PS: If I install them offline, the airports work, but GSX and GSX2 don't.
