ozpost shipping module

[pawspoint]

Hello Rod,

I've been using the ozpost contribution for over 12 months on my site very successfully.
I am running Zen Cart V1.3.8a using Bluehost for hosting. I use ozpost contribution v1.0.2 April 2009. Sometime Friday morning between 12:29am and 8:42am the postal quoting on my site stopped working and instead returns the error for all postal quotes:

Aussie Post ( Unexpected error (no valid methods). Using AP Flat Rate.)

There have been no code changes applied to the site for at least 1 month.

I've trawled through this forum today to see what others are experiencing and it looks like I am not alone.
Could you please provide advice on what I should do.

Does the ozpost contribution ultimately call web services provided by Australia Post? Perhaps these have changed Friday morning some time.

Will the most recent version of ozpost solve the problem and does it work with the version of Zen Cart (1.3.8a). I note the contribution section says the current version works with v1.3.9.
