1. I have bought few ebooks from kopykitab.com
  2. They have their viewer for pc.
  3. i can open the pdf in their viewer by logging in kopykitab.com withou any password and even without interenet (once pdf id downloading inside viewer.) Later it can be viewed offline.
  4. but PDF which i could get it, hidden inside the some folder in pc cant be opened in adobe. it is asking for password.
  5. Any idea what could be the solution?

I am facing the same issue. Have you got the password?

is it possible to read the ebooks online on their site? if yes then its possible to get pass.
