Hi Carlos, welcome to the forums
Your ISP may be providing instructions for Outlook rather than WLM, so don't worry if you can't find the tools menu - you should be able to add your mail account using the following tutorial :
http://explore.live.com/windows-live...il-account-faq. In WLM 2011, just click Accounts > E-mail and then enter your e-mail address and password, it will try to auto-detect the settings.
From what I can tell, all of the settings you need to enter are listed on this page:

The walkthrough is for Outlook 2007, but the settings you need for POP3 servers etc... are all there. I don't think you'll be using "aliceadsl" as your username - it will probably be your e-mail address.
