Hello Nadine,
From the screenshot, it seems that you're running the old version of RouteFlow. There's a new, refactored version with some new features. You can grab it at GitHub (https://github.com/CPqD/RouteFlow) or download a pre-configured VM (ftp://ftp.cpqd.com.br/pub/routeflow/RouteFlow.zip).The tutorials have been converted to automated scripts. The README files in the VM package and inside the RouteFlow directory will help you run these scripts. For the pre-configured VM, you should go to the Running section in the RouteFlow README (you can skip the "sudo ./create" step).If you are interested in running the old version of RouteFlow, let us know.Allan
