Hello Archon,

The problem is only with your Internet browser.

Please clear your browser cache (check the help topic from your specific web browser software), close it, then log back into the game.

It happens quite often because Adobe Flash uses too much memory and is prone to crashing. In your precise case as you described, you have to clear the cache to flush your computer memory and browser cache on your hard disk, that are currently clogged with corrupted files.

You'll be back to normal behavior, until next time - but now, you know what to do. :)
