UPDATE: Looks like everything is back to normal. Sorry for the interruption or problems you all may have had.
If you are experiencing issues with dictionary downloads or the leader board screen, please be patient. These items are hosted on a web server and the hosting company is having problems today. If you are doing a fresh install of Word Mix (Lite), the game should detect the server being down and automatically default to loading the "built in" dictionary that comes with the game. Again, I am sorry for these issues, but they are out of my control for the time being. Please be patient and I'll post something when I see that things are back up and running properly.
