From the Knowledge Base article about "Second Life cannot be accesed from this computer":

You cannot log into Second Life from this location

This error message may also appear as:

• Login failed.
• Second Life cannot be accessed from this computer.

These messages generally indicate you have been blocked from the Second Life servers by Linden Lab as the result of:

• Documented cases of fraud
• Use of Second Life by a minor
• Exceptionally flagrant abuse activity

Note that someone else in your household may be responsible for this activity, not necessariliy with your account. 

If you believe that this is an error, submit a support ticket via the support portal. To help customer support determine what block has been placed and why, include in the ticket your Second Life account name and any Second Life accounts that log in from your location.
