I am suddenly having the same problem,it just will not connect at all. It just sits there saying it is connecting to the network and nothing happens,I tried every single tip and trick posted in here even downloading frostwire and that connected just fine,then I tried limewire again per instructions and still nothing happens. I even unistalled limewire and reinstalled it nothing is working to fix this connection problem. I haveused limewire for years but I am ready to just keep frostwire in here instead at least it works.

I tried disabling the oob searching to and it didn't work.
I checked all my firewall settings and they are fine,I just plain give up I am at a loss,nothing has worked to get it to connect.
