Hi I have recently installed the AustPost Improved for shipping for a friend on her zencart site www.alittlebittarty.com/index.php late last week. I am testing today having tried adding weight for one product and when I select checkout I receive the following message

ERROR:Unable to obtain a valid quote from the Australia Post Server.
You may still checkout using this method and we will contact you with postage costs as soon as possible.

In the shipping option I have notice that the "AustPost" and "Zone Rates" are both green but I'm not sure what I've done wrong........ can any wonderful person help help help me...pretty please? I don't get where I've gone wrong :o(

Thanks heaps
