Currency not changing

Hey everyone, my first post on this forum
Have done a quick search and couldn't find anything so I apologise if this is old ground I'm covering...

I've installed Hikashop and love it, but I'm having a small issue.
When I create a product and specify $AUD, it all saves and looks fine in the back end. But when I view the shop front end, it'll display the product price as 35,00E (AUD35.00).

I've already disabled ALL currencies except for AUD in the dashboard, but it still seems to show up on front end.
I've even tried editing the module with the option "show price in original currency = no" but when I do that it ONLY shows EURO, and the AUD price disappears!

Please help me :'(
