Cant use cadence PCB's auto-router option

Hello everyone. I'm new in cadence products. I wonder if there is a way to solve the following mistake. When I had all the electronic devices placed on the PCB, and I want to route all the tracks but not manually because there are a lot of them, so I try to use the option "Route->PCB router->Route automatically" but cadence throw me a message that disable the "Route" option.

"Please verify that you are running allegro pcb router version V9.0 or later. try "file viewlog" to view Allegro PCB rpouter's log file"

Thanks in advance.

I had same problem before, but I found the cause! when I removed all of Clines and Vias on the board, it works correctly. if there are the clines or vias that I created by hand on the board , it happened kind of that problem in my case. it has some bug I guess.... (I used professional license)

Last time I used the AutoRouter there was a check-box "Protect Routes/vias". When this is set, only unrouted nets will be handled by the autorouter. An advice is to route all critical nets first such as clock, power, create planes, etc and leave the uncritical nets to the autorouter. If you make a save of the half-way completed board, you can use a copy for experimenting, setting the layer route preferences, cleaning up via options, etc. It was some time since I used it (OrCAD Professional), but I think that constraints created in CM will be honored by the router.

Even if the routers are quite clever, I have always had to spend some time in a manual optimization of routes afterwards.
