How to pass this phase, thank you_S
to be able to use IutSystems you need both the development environment, which is what you have opened, and a server. If you're working to an Enterprise, they will have to supply the server name and a valid user + password. If you're just trying it out, like in a Personal Environment, you can check the details in http://www.outsystems.com/home/. You'll see the details of your PE and you can log into it with the same credentials you use to log in to the forums.
