Trouble opening a PDF that connects to online server - Network Error

Hi everyone,

This problem has been bugging me and I've tried to change the settings a million different ways but it just doesn't work. Please help!

I've been trying to open a Fillable PDF file that connects to a online server (to obtain information) using Adobe Acrobat X Pro, and every time this error message shows up:

Network Error
NetworkError: 0

operation: getOrganismPartTypes

Unable to establish network connection

But I can go online no problem so I know it's not my internet.

I can open regular PDF files no problem.  I tried to change the security settings and add the server and the file onto the safe list but it doesn't help.

Anybody can help me out?  Please advise.

Thanks so much!

M
