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?
