Cannot Connect

About a week ago my LimeWire suddenly decided to stop connecting. It is currently on the 1 green bar and saying that is currently connecting to the network. The globe on the bottom of the screen is NOT blocked by any firewalls and I looked at my anti-virus programs to make sure they aren't blocking anything. I have tried to use Bearshare in the interim and that is able to work but I prefer LimeWire for obvious reasons.

Now I am on the school network, but it worked fine for the first 6 weeks I was here at school and then last week it wouldn't connect anymore. Any suggestions?

anyone?

Any chance that the school's stopped allowing p2p use? Can other people use LW at school?

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.
In case you're using Vista: LimeWire Pref Folder in Vista

Had you updated Java around the time that LW stopped connecting? Try this Java version. Download the JRE offline installer & remove any other Java versions before installing this one.

In LW tools > options > advanced > firewall config. Change LW's listening port to 64049 (or try others in the range of 49152 - 65535) > apply > ok.
