I tried to avoid going this route, out of deference to LimeWire, but if a reinstall doesn't fix it, and LimeWire support leaves you hung out to dry, and nobody else comes along to help, then try this:
The program I am using is called Acquisition. You download it and run it right from the desktop. No installation necessary. You need to be running at least OS 10.2 to use it.
The beauty of it is that the developer has added an iTunes preference, which allows you to automatically add downloaded songs to your Library, and play them if desired.

(They have a great forum too!)
A side note: A few people ( I am one unfortunately) are having problems running the newest version. Many others are not. You'll know if it crashes repeatedly. But it is worth a try in my opinion. Before this minor bug, which will be fixed soon, I was able to run the program for weeks without any trouble. I had to revert to a previous version, .9 as a workaround. But that will not be an option for you, as I don't think it can be downloaded any longer.
And please, whatever tidbits you learn, come back and share so others may learn, and I and others will know how you fared.
Good luck.
I'll be gone a couple of days. In case I don't respond, that is the reason.
