Please help! (Can't Connect)

I downloaded SL and when I try to connect it says
"We're having trouble connecting. There may be a problem with
your internet connection or the Second Life servers.
You can either check your internet connection and try again in a few minutes, click
help to connect to our support site, or click teleport to attempt to teleport home."

My internet seems to be fine though, and my friends are on SL so it's not the server.
Anyone know how how to fix this? ):

May be a dense question but you DO have high speed internet access, right?

Edit: Also check if you have a firewall software running that may block your access to SL.

Yes, I have high speed. And I do have Kaspersky Fire wall, I tried turning it off but it still wont work.

Some firewalls are pretty persistent in their settings, even when turned off. Did you check the build-in Windows firewall, too?

Only other thing that springs to mind is, are you on a wireless connection? Some users have reported they have trouble with SL on wireless. Not all of them but it might be a possibility.

System specs, type of connection and such might help us in finding the culprit here.
