Splinter Cell : Double Agent can't find ndas file

i tried to find dnas files from scda, i found few files but disk id insertor couldnt open the files.
anyone getting same problem?

Try using WinDIP. It will patch the correct files on the iso.

And this will make the game work from HDD?

nope it won't, the dnas code has nothing to do with that.

And you cant play online games from the HDD either, unless they specify that you can - which only applies to about 4 games.
