[Why does it keep telling me that Second Life can not be accessed from this computer?]

It won't let me into my Second Life account. I entered my log in information properly but it keeps telling me that Second Life cannot be accessed from this coputer. I never got a notice saying that I was going to be banned from Second Life and I have no idea why I would be banned. I need help as soon as you can please. My account name is Deffender2579. Thank you.

[Help me please. It won't let me log in.]

It keeps telling me Second Life can not be accessed from this computer. It let me in yesterday but when I relogged after 2 minutes it kept saying Second Life can not be accessed from this computer. Please help me
