Nikki, you are tenacious like bull!!! LOL
I had the issue once many months ago, but all I had to do was log off and log back on to see my messages. It went away/corrected itself when I updated my browser (I think I was using Mozilla at the time). I highly doubt it had anything to do with the solution, but I am not computer-savvy enough to say, and upgrading is always free, so give it a shot! I hope you get it working soon.
