Maybe the email isn't working. Did you try using a another email?
Is it a regular contact form or does it use PHP?
I am guessing the STMP or PHP mail is down for the server you are on... I suggest you try another contact form to see if it works.
I think that its my aol email that is blocking it. I changed it to send it to my email address at my website and i have my email there forwarded to my aol. lol So It works now! lol
