How do I pay my MYOB subscription?

I need to pay my subscription.  I get that it will be a monthly payment now instead of an annual one but when I attempt to access "View Invoices" under "Subscriptions" in "My Products" a message tells me that page isn't redirecting properly and sometimes caused by disabling or refusing to accept cookies.  Have tried again several times and no change.  I don't know what this means or how to get my invoice.  My sub expires soon and I need to upgrade to the latest.
