How do I make more room in my account?

I am not sure that I understand your question correctly. Could you please provide us more details of your concern? At that time, we can assist more properly. We'll wait for your response.

I put up another post.  I pay for a subscription, but it says I have a free account.  That's not the case.  

Thank you for your response. It seems my colleague solved your issue at the following link:
