All-Time Sudoku now requires a key

[Post New]by Old_Salor on Feb 3, 12 11:25 AM
I just re-installed the game after a time away and got the following in a pop-up box -
"This program requires a security key. If you have one, select OK to enter it. After entering a valid key, you will not be prompted again."
I have no key, and don't remember ever having one. Does any one know what this error is or how to get the proper key for an already purchased game?
