Sometimes the system does have little hicups.  Normally happens if you press the preview button.  I have unlimited uploads and even i don't press the preview button.  You will now have to wait a full 24 hours or at least to after 2.00am site time when the clock resets and try again, if this happens again let me know.  I will contact the programmers and let them know that you have a problem
