Do you have any logs in your "Runtime data" folder? Also, does anything happen if you actually try going into a game?
To be totally honest, since I've not yet heard any reports like this at all, I'm thinking it's possible that your install got corrupted somehow. You may need to try re-installing the game.
The second screen shot was from "in-game".
I uninstalled and tried the 1.0 installer. It seems to work fine so I guess something must have gone awry when updating.
However, when I ran the game directly from the installer, the dialog box at startup prompting for a key did not have text labels on the buttons below. When I quit and re-ran the game, they looked fine.
