Hello,
I unrouted some tracks manualy and now I want to route all of them with autorouter, but nothing can be routed; it tells me I have 179 unwired, and existing vias get disconnected.

and here is the file https://drive.google.com/file/d/0B8-zPR9xLcQET1BpS0loNmxwUms/view?usp=sharing

I was doing it with Pulsonix 8.0 5536

All the nets appear to be locked. When I unlocked them and unrouted the whole design I was able to run the autorouter. The autorouter wasn't able to do much with it, because of problems with the layout.

The problem is,
I am using autorouter as suggester and I first do autorouting, then, manualy correcting tracks autorouter cant do. And now I have half-routed board, and I want to use autorouter and I cant.
And after a while tracks are not visiable anymore, exept when I try to manual route then I can see where those connection goes while I am moving mouse.

I'm using latest version 8.5, I don't know if that is why it worked for me.

After a couple of goes, and leaving your original routing, the remaining nets routed OK. See image:

Maybe I should use 8.5 but it looks like it is not posible to update from 8.0 to 8.5

It was doing too many passes and was taking forever. I reduced it to 5 passes, and cut short the track length optimisation.

You can upgrade to 8.5 if you have maintenance. I doubt if that is the problem, though.

Advanced autorouter didn't work for me, either. I assumed you were using the standard one.

I think I figure this out...

My previous pcb was with poured copper, and then I add some components to schematic and sync it with pcb, but before syncing I deleted pour templates both top and bottom, BUT, I forgat to REMOVE copper FROM NET and it looks like pulsonix wants to connect to poured copper which does not exist anymore, but now it is imposible to remove poured copper from net because it does not exist,

I think.

I've found the cause of the problem - you need to place a board around the components! When I did this the Advanced Router worked OK and the remaining nets routed 100%.
