Error whit the game :( help!

[Navael]

Well, im new in B&S, i download it yesterday and installed today, i run the game but it send me an error that say "Invalid game client file. "Pleaase update the game client or reinstall.(2000) (193)"
I was trying to got infomation from the internet but i didnt find a helpfull answer. I already try the repair system of B&S but nothing.
i have 2 units, the C// and the D//, i save the game in the D// but it wass installed in the C//, so i cut and paste the folder "NCWest" to a new folder with the BnS folder, so now are one folder with two folders inside.
