Where can I access Visio Stencils in .vsdx format instead of .vss?

[bkmerv]

I have the latest Visio Professional License and I need to use Cisco Visio stencils for a project. The .vss files that the Cisco site provides are not supported in my organization. I receive the following notice when attempting to open them:

"You are attempting to open a file type (Visio 2000-2002 Binary Drawings, Templates and Stencils) that has been blocked..."

Does Cisco provide newer versions of these files somewhere?

Thanks
