Old version of Limewire needed

I recently downloaded - at Limewire's suggestion - the latest version of Limewire 4.14.8 (I think). It created problems with my Norton anti-virus software. I spoke to Norton and thought that the problem was solved, but it wasn't. Getting Norton on the phone takes ages, so I thought that I would download a previous version of Limewire 4.12 perhaps, but I can't do it. The only file that I can find to download is a Limewire.exe file which when run manages the installation of the latest version only. Is there any simple solution to this or am I going to have to spend all day on the phone to Norton?

Found an old version - thanks to anyone who spent time thinking about my problem. Writing out and posting was useful - I started asking myself what I would suggest if the same request was made to me. Then the answer was pretty obvious pretty quickly!
