Error While Converting .doc to .pdf

Hi all

I am using Adobe LiveCycles PDF Generator ES (adminui) to convert .doc files to .pdf but I am getting the following error:

Error Code:1000
Error Message: ALC-PDG-001-000-Conversion failed because of an exception. RuntimeException; CausedByException is: An unexpected exception while resolving a new connection to an Adobe Service.

I have installed both the ALC ES and Microsoft Office 2003 respectively from the same user. Please help how to resolve.

Thanks in advance.
