My Woo-Multi Currency Plugin is not Configured Correctly

Hi, I have purchased this premium plugin for my two websites http://www.platypusdreaming.com.au and http://www.kayaxan.com.au.
I am unable to update this plugin. The code is added correctly to my website, however in the backend it is showing that it is “verifying” (it wont say verified). In the villatheme settings, its only showing that its connected to tamsine.sg-host website (very old website). I don’t think it’s been configured correctly on either of my websites. Can you please check and let me know how I can configure this correctly?

Also, on my website http://www.platypusdreaming.com.au the prices are automatically loading in USD. After about 10 secs, they switch into AUD (I am based in Australia). However it doesn’t matter how many times I open the website – even if I open it 50 times it is still doing the same thing. It’s affecting user performance.

I look forward to hearing from you.
Kind regards,
Tamsin Edmont
