I have tried everything from Limewire to Mactella to Phex to Napster. I tried allocating more RAM, but they all crash or freeze. Let's face it, Macs are great but the availability of a good file sharing program is horrible. I just downloaded Aimster and it seems to be working great. As for the availalbility of files, I found some pretty obscure stuff, so I think it will work great for me. Try this one out, I think I can finally stop stressing. Yay for Aimster!!!!
