Sorry about that, I read your first post completely wrong

So are you seeing any green connection bars, or it it just 'starting connection'? Do you see the firewall icon (brick wall in front of the blue globe)? What's changed since you could connect (hardware, ISP plan, new software, updated software etc)?

Read through this thread, it has a lot of info. Make sure your firewall's still configured properly. Do the port test & see if it works.
Connection problems? Check here first!

If you don't find any help there, post back with your details. Post #2 of that thread tells you the info that we need.
