If you mean Mercedes Benz Truck Racing, I'm pretty sure that the last nocd available is 1.19Beta for the international version, 1.09Beta for the German version. It's very, very hard to find those beta patches, so in effect those nocd's are useless. I think the last official patch is 1.10, but there's no real copy protection in the game, only a cd check. So I'd advise to install the latest patch (probably 1.10, maybe different for the german version) and make an image of the cd with clonecd, and mount that image using daemon tools. This will allow you to play without any cd at all. You could also just copy the cd with clonecd and use the backup, as I said there should not be any copy protection on the game. Have you tried copying the cd and using the copy ? If not, try it, before your original gives the ghost
