Why? What happened when you tried? What error message, if any, did you get?
Your best option to resolve this is to follow my original advice (or Hannah's reiterating mine). You can absolutely contact Support through the ticket system for any billing or sign-in issues, regardless of the account type that you have. Make sure you're NOT signed to ANY account in when you do it.
