I searched for the .limewire folder to erase it and change it

I included all hidden etc folders
nothing was returned?

I was using a version of limewire that WAS working, and it wasn't connecting before so I updated Java and that worked
but then it stopped connecting again.

I uninstalled LW and Java, reinstalled, reupdated (after trying without the update) and it never connected.

I'm using an Avast! firewall and webroot spysweeper.
