Trying to purchase premium version fails

I am trying to purchase your premium version but can’t get to my cart to purchase. I have registered as a user. But it keeps coming back with this error when I click to see my cart:
You have reached our product forum page.
Purchase is required to gain access.
If you purchased the plugin, you are automatically granted access and can login above.
If you’re unable to gain access after logging-in, please contact us here.
<<please contact us here.>> this also gives me the same error.
