Cant get NEW emails.

[550gts]

I have the Droid 3. I had my att email setup when I first got my phone. A couple weeks ago, I had some virus trouble on my email on my pc and had to have my email password reset. I put the new password in my phone but I still can't get my emails on it. They only go up until Jan 9. I've searched around the forums but haven't really found a solution. Can anyone help me out? Thanks in advance!
