Oh ok, I have understood.
Now I deleted also another program called "cdclone" or something like that, and also the second file exe tells me the same message as the first one: "insert the right DVD-ROM, select "OK" and restard the application."

(I searched about it on the web, and I found a girl who has the same problem, but her DVD isn't original!!! A boy wrote to help her, and explained that she has to paste the file "crack" of her DVD in a "handle" (i don't know if it's the right english word xD) in "Programs".
So, do u know where can I find the crack-file?
Or how can I say to my pc that the DVD is original... xD
