Mike, are you just updating the version using the TC Admin panel, or are you replacing your. srv files with newer versions too?
With the ever-changing updates, if you aren't updating the srv's with ALL of the commands, itcould cause you issues.
Also, make sure you cleanly disconnect Airio b4 you update the version in CP, type !quit, or it could damage your sta files, and you would need to replace them with a backup.
