Could you please clarify?
Did you purchase a $2.00 Supporter package? If so, this does not give you any additional hours, as clearly outlined on the upgrade page and FAQ guide:
Tutorial - Billing and Payment FAQ
I've paid $2.00, why do I not have more hours?
A single $2.00 payment will only give you Supporter status, it does not increase your hours allowance. This is made explicitly clear during the purchasing stage, where you can increase/decrease your payment and accordingly, your hours allowance.
If you have made a single $2.00 payment and want more hours, another payment of $2.00 or more will increase your hours.
