Error in Connecting to Environment

Hi, I'm new in Outsystems and I've just installed the Service Studio and when  I'm trying to connect to environment, it gives a communication error : "There was an error contacting '': Invalid username/password."

I use my login credentials in my username and password as the other people suggested, but it seems it doesnt work on mine.

As for my whole installation process:
1.  I sign up in
2. Activate my account 
3. Download the Development Environment
4. Run the Service Studio then it prompt the login of Environment, Username and Password

Thanks in advance
Hello Lui

When I attempt to access the URL I'm redirected to the OutSystems Home page.

This is usually indication that your Personal environment is either in maintenance or it was stopped.

Can you access the OutSystems Home and check the status of your personal environment?
