hi Jacinta,
I probably know as much as you do in regards to this module.
I have not installed it yet.
Generally all Mods have a support thread.
Sometimes this is shown in the read me file.. otherwise when looking for info on a mod do a search in the forum or google for zen cart the mod name and support thread.
I had a brief look for Aus post one but have not found one yet.
I'd probably go through the read me file again for the MOD and make sure your confident all the steps were followed correctly.
Muz
