Mail

Hello,
I've been using my Mail application for a couple years now without any trouble, but the other day it stopped working. well not completely, but i can't receive emails in my Mail anymore. any ideas why? i have a gmail account and haven't made any changes to it recently....attached is a screenshot of what I have fill out for my Mail preferences account info....anyone have any ideas?
thanks a lot for the help!

hey, i've been trying some stuff and I ended up just deleting my account that wasnt working in my Mail and made a new one which seems to be working fine so far.....i guess i should have tried that before i put up my question!
thanks anywho
