Recently got Visio 2013 and now I can't open some files and hope there is a work around. One file for example is one I got here "FunkyLinePatterns.vsd". I get this this message in a pop-up:
This error occurs when you open a Microsoft Office file type blocked by File Block settings in the Trust Center. To enable this file type, do the following:

Click Options.
Click Trust Center, and then click Trust Center Settings.

To open documents with this file type, disable the registry policy setting. For more information, see Microsoft Knowledge Base article 922850.
