Thanks John. Several updates to windows os and updated AICARS through Navigraph, and other misc updates and it seemed to work as advertised this am, so potentially associated with required updates/upgrades. Thanks for offering to assist. Will keep you in mind for future need. Mochas Gracias Amigo!

I have FSUIPC7 running as the batch file to auto start MSFS. I used all default settings for FSUIPC when I downloaded it. Prior to the upgrade to new version this am I had similar problems of non-connection. This was both pre- and post MSFS World Update to Canada. I have successfully completed 7 + flights using FSUIPC7 and Walker Air Smartcars app and then it stopped working within last few days. No pc changes that I know of. Ayuda-me for favor señor Espana!

I have had MSFS since 2020 release. I have been using smartCARS for a month, and just 2 days ago got the Simulator Connection Error. I downloaded latest version after this (7.3.11) which required uninstall of 7.3.03, and loaded fine. Also now registered the program. I still have connection error. Any assistance? Within the opened smartCARS for Walker Air Transport, I am connected to the world as it does see a pre-bid flight details, and I can chat with others on the network, so what is missing?
