Had SLI working, but broken w/forced driver update.

Before this last update here's what happened.

1. Installed game and opened.

2. Got an error saying to use driver ___ or newer.

3. Installed the driver and opened the game.

4. SLI did not work.

5. Searched forums found driver version that works.

6. Installed that driver (older than required on initial install so not sure ho the game let me us it) and SLI worked.

7. Had to update the game.

8. Got the error saying to use driver ___ or newer.

9. Updated driver and SLI did not work.

10. Installed previous driver and got the driver error again saying to use newer driver.

What is the solution to this? An older driver works great. I had no problems at all, but now I am forced to update to a driver that does not work with SLI.

Any help on this would be great.
