Maybe your credit is split between sats and cowboy credits, and the no one of the two balances is enough to publish. What do you see when visiting this page /credits ?
Another thing you can do is to disable the freebies option in your settings page, so you will be able to post freebies. Just consider not all territories allow freebies and they will also have much less visibility than normal posts.
