Hey Brandon, yeah they are email I got from them:
At long last I’ve done it! You were correct in saying there was no MySQL evidence in the phpinfo. That’s because the extension wasn’t installed. Anyways, I feel a complete prat for not spotting something like that sooner. As we have dedicated servers I didn’t have something like Wampserver to rely on in terms of getting the right components installed - that’s my excuse for not installing the extension anyway!
I managed to get our hosts to give me the name of the DB server so that I could use it in the installation - it was just a case of using that plus the port number.
