Help (won't connect after reinstall)
 

My operating system crashed and I had to reinstall limewire. After setting all firewall and system specs it still won't connect! Any help out there?

Try the advice in this thread. Make sure that you read the whole thread first, then go back to the start & try the fixes;)
all of a sudden will not connect

First of all, delete LW's preferences folder & update/change Java...they're often the things that will fix a connection problem with a minimum of fuss, especially after reinstalling or upgrading LW.
