I'm getting a "Server could not handle the request" error message when I try to "Subscribe"

Benson:

I’ve tried logging in/out but its saying I’m still on a free account, I click subscribe but it gives me error message ā€˜Server Could not Handle the Request’

I’ve tried the remedial stuff, log in/out, clear cache/cookies, restart etc but no joy so far…

But I have subscribed and have credits left? It did how these at the top but for some reason its showing me as a free account now
