This can occur when a third-party application, ZoneAlarm (OR ANY OTHER PERSONAL FIREWALL PRODUCT), is installed and enabled. Even if you are not trying to connect to a multiplayer game, ZoneAlarm knows that Scrabble Complete is capable of multiplayer play and will try to bring up a window asking if you want to allow Scrabble to connect. On some video cards, the computer will have trouble redrawing the screen to show this window and eventually will fail with this error. You will know this is the problem if you can see hints of the mouse cursor in the lower-right corner of your screen when you move the mouse. To fix this:
Open ZoneAlarm (OR ANY OTHER PERSONAL FIREWALL PRODUCT)
Find Scrabble Complete in the list of applications and allow it both Internet and Server access. (Contact ZoneLabs (OR MANUFACTURER OF PERSONAL FIREWALL PRODUCT) for details on how to do this if you cannot do it yourself.)
Restart the game.
