Error in Policy Settings in MSWord, WorkPlace Concept

Hello techyv users, I need help on this:
I received an error message when you try to open a file type that was blocked by your registry policy settings in Word 2010, in Word 2007, or in Word 2003 In Enthusiasm Workplace Concept 2010, Enthusiasm Workplace Concept 2007 or Enthusiasm Workplace Concept 2003, I attempt to start a program that was stored in an Enthusiasm Concept structure. As I applying this the submission does not start. Furthermore, I get one of the pursuing problem information:
You are attempting to open a file type that is blocked by your registry policy setting.
Any help will greatly be appreciated.
