Save Game File Error

I posted this on Vista.games, but I thought maybe I should ask in this group
too.

This started a couple days ago. My computer did not lock up or lose power,
so I'm not sure why it's happening.

Anyway, whenever I reboot my computer both FreeCell and Spider Solitaire
automatically open with the same error message on both games that reads,
"Save Game File Error." The save game file was either missing or invalid.
If
the file exists it will be deleted. A new game will start." When I click
OK, a new game starts.

How to I prevent this from happening? I do not have any saved games in the
save games file.

Thanks,
Amanda
