It doesn't work properly. Works the first timeI use it, then it freezes the game and I have to use CTRL/ALT/DEL.

As a follow up to this. Is it possible to do a rolling back up, to help prevent losing a save do to file corruption? Something similar to FM?

"Save As" is still not working. Try it. It may work the first and 2nd time but after that it locks up the game.
