Do U know why my neverwinter nights isn't working

[jnc007]

I've got neverwinter nights and I want to use a No cd key, however, the two I got that I know work are not working. I've never used one before. I load disk 1 and 2 with no problem. It then asks fro disk 3. however even after I drop the no cd crack in it still wants the disk and I can't finish loading. Anyone want to try to walk me through this?

So, this is not the original game, right? Sorry, but we cannot discuss cracked or pirated programs here.
