You need to stop posting all over the place. It's a PITA & is against the Forum Rules.

Some people have had connection problems when using Java 1.6.0_01. Try this version instead. Use the JRE offline installer & remove your current Java version before installing this one.

Something is blocking LW's default port...possibly your ISP? In LW go tools > options > advanced > firewall config. Change LW's listening port to 64049 (or something in the range of 49152 - 65535) > Apply > ok.

If that doesn't help, delete LW's preferences folder when LW's properly closed. See point 3 here & also point 2 if you've used older versions of LW in the past (there could be a folder in either location).
Fixes for LimeWire
This will kill all of your settings within options, you'll have to go back through afterwards & reset things. If you're not sure of your settings, go through LW's tools > options & write them all down, so that you can reset things later.

If you want to get rid of the firewall icon, try port forwarding for your SBG900. The instructions are here.

Don't forget the step of setting up a static IP address first. LW's listening port, port in the 'manual port forward' box & port forwarded within the SBG900 all have to be the same number.

I'd also suggest you get a software firewall. There are good, free ones around.
