Thanks. And what a story!

I went to the site and clicked to download 4.1.2. A message told me that this would erase the 4.1.8 that was installed. I continued. Then a message appeared that there was nothing to download. So I tried to download onto my LaCie disk. This worked, but it was the strangest thing. It downloaded 4.1.6 Pro, which I had previously before I mistakenly erased it.

There are gremlins at work. (*_*)

To install an older version, there's a file in the main OSX Library that needs to be removed first.

Open the hard drive, open the Library folder, then Receipts, then delete the file called "Install LimeWire.pkg"

Now you can install an older version.

There's no need. I'm working Limewire Pro 4.1.6 from my Roxio drive. I think that the hard disk backup on the Roxio allows this to happen.

Thanks.
