Paypal charging Australia International when its local (v1.3.7)

Hi ,

I have Zen 1.3.7 (please dont tell me to upgrade as my next upgrade is in March). I have Paypal Express checkout (V0.1b) and all has been working perfectly until a few months ago. For some reason when going through Paypal it only displays the postage as Australia Post International when the customer is in Australia. I set up a dummy customer in Australia and selected direct deposit and the postage was available (international post had an error against it which means I coul dnot select it) and the other options were there. But when selecting Paypal it took me to a paypal site and I filled in the details and then it took me back to Zen with Australia Post International already selected with no other options...???

Any ideas with this ???

Thanks
Dave
