Thank you for reaching out, Shivam. Regretfully, the solutions offered above failed. I am using pdf995 now as Adobe Acrobat has crashed on me too many times and the support help is negligible. Answers on forums, especially from Adobe staff, are written in language that is hard for average computer users to understand. pdf995 is not as smooth a program to use as Acrobat, but it works all the time and their support is fast and complete.
