I’m frustrated

T-Bird says my inbox is full, yet I have ZERO messages ANSWERED: usually fixed in 3.1.7 by right clicking folder and selecting "Compact"

I get the following message from Tunderbird:

"The folder Inbox is full, and can't hold any more messages. To make room for more messages, delete any old or unwanted mail and compact the folder."

My inbox is empty and I've tried compacting it several times. I've been running Verizon FIOS on a Windows Vista machine for over a year now without any problems. Nothings changed on my machine except now I can't get any messages. Can anybody help?
