I had trouble for months (okay, I didn't make it a priority though) and tried everything I could find. I finally found this answer on a thread and it worked. It's quick and easy to try, so you might as well try this before you start uninstalling, deleting and all that other stuff.

In windows (I have XP)

Go to Start My Computer
Go to c:\programs\program files\limewire
then click (or double click) on the file that reads
limewire.jar
and under it says executable jar file

Once I clicked on that, i went through the short setup language thing again and it worked fine!!!!

I read on another post that enabling limewire on startup caused problems so i deselected that.

Also, i had windows firewall on with limewire as an exception and earthlink (dial up) firewall off.

I just put a shortcut of the jar file on my desktop. I need to download some fleetwood mac before i start worrying about icons...

So I'm going to post this in a bunch of threads in case it helps anyone else.

I got this advice from another thread so thank you to them!!
