Reinstalling makes no difference. The error is in the current update. It doesn't recognize metric system.

Best you can do is use flat rate for international (put big value in) seeing as you cant actually specify Aus only when using TL. Uploading, then going to listing and revising to what you want.

Currently you cant use calculated international rate in TL, and you cant specify Aus only.

If you have an old TL exe file you can uninstall then reinstall using old exe then use back up data from current one.
