Since I upgraded to Word 14.1.3 it blocks every Word document that I get sent by email. I have tried all of the standard recommendations (opening using the File Open sequence and everything Microsoft has listed on their site). The same files open on my other Mac and on a coworker's Mac that also has Lion and 14.1.3. There must be some security setting but I can't find it (I have checked the preferences on Word and this isn't the issue). Any ideas?
