Here is a copy and paste from my own post on this, but same here!
I lost my message center yesterday around 7pm central time. I had 17 cosmos sitting in it because I wanted to get an estimate on the link limit (until I saw the forum post about it). I have had over 50 items in my message center before and it hasn't been a problem, this has only happened today. I had not posted the link for cosmos on gaia, so the only ones I had received back were from friends.
The message center does not appear at the game start up on either firefox or google chrome and when I click on the message center icon at the top of the game page nothing happens.
I am running Windows 7(64 bit) / Firefox 12.0.0.4493 / Google Chrome 19.0.1084.46 / Adobe Flash 11.2.202.235
I have tried restarting the browser, logging out, restarting my computer and back in and nothing.
Thanks, I've done the same things as you, I even tried the newest IE, and that didn't even work.
I'm starting to think that none of the staff have even seen this thread, no one has posted saying they are working on it or saying how to fix it.
