"vias not enabled for routing"

Version 1

    I've been using PADS since October, so I know it pretty well.  I've been working on a complex layout for a few months.  I just updated my via sizes to match what our manufacturer will implement.  All I had routed was power and some fanouts.  Now, most of my vias are not connected to the fanouts.  They are still there, but not connected.  I tried manually routing and I can't add vias.  I've checked all my settings and I cannot find the issue.  I keep getting "vias not enabled for routing" message in the router.  I don't even get a message in layout.  Any ideas what could be causing this?
