Can't get PartQuest in xDX design to open

Hi,

I am using xDX designer  VX1.1. When I click on the PartQuest in tools drop down I get the error message "Decryption failed: Direct Download users re-extract your .pqz file to ensure you have your part information and pqd.bat present. I extracted the part file where do I put it? I can't get anything to work.
