Save as Adobe PDF... in Print funciotn will be not respnoding...

Open a word file, Print -> PDF -> Save as Adobe PDF -> option : "High Quality Print"  and "Adobe Acrobat Pro" -> Continue -> change Name and location -> Save. Then the "Save as Adobe PDF" Automator pop up on Dock, a "Save as Adobe PDF" window will show "Finalizing PDF file..." and not reponding......... have to Force Quit.

But, if I use "Save as PDF" on Print, it works but will creat a very large PDF file. For example, my DOCX file is only 270KB, the PDF will be 23MB.

Open the PDF with Acrobat Pro 10.1.8, Save as "Reduced Size PDF..." -> make compatible with "Retain Existing" (tried all in the list) -> change Name; -> Save. Then, Acrobat will be nor responding on "Analyzing document....".
