Chess Titans now no longer working and today there was an update and I suspect this may be the reason. Chess Titans is displayed on explorer as unspecified.one of the updates is about nVidia graphics adapter.request help for getting the game restored thanks
The nVidia update is a new driver; not a true Windows update as they are normally known. Open your display adapter and choose the "Drivers" tab. From there choose "Roll Back Driver" to revert to your previous display driver. The above action won't "restore your game", but it will put you back to the nVidia driver you say was working ... if the older driver wasn't uninstalled. If it was uninstalled, you can always get the video driver that worked from the nVidia website. All you need is its version number. Something like 275.33. If after the roll back you still have problems, the solution lies elsewhere. At any rate, you need to check with the game's maker and get their take. There may be an FAQ section on your exact problem or you may need to contact them directly.
Roll back to a prior restore point and simply don't update your drivers unless they absolutely need to be. I know how you may feel; All my drivers and system drivers need to be up to date if there are newer ones available. Did you update through Windows Update, NVidia Forceware or NVidia's Website?
