private message gone missing

Hi, I logged in a couple of days ago and had an e mail to say I had a private message in my inbox, which was sent 8.7.09 at 12.41pm, it was showing 1 next to the inbox on icmeleronline site, when I accessed it, there was no message. Just wondered if it was a blip, wouldn't want anybody to think I'd ignored a message sent to me.
Thanks
