Thats annoying, i did think it was rather pricey! The old version of Pro i got through the originally paid for Limewire, it worked fine until i deleted Java, unaware that it ran on it! I re-downloaded Java and everything and eventually the second version of Limewire i got, the newest version from the official site worked until i used it to download Pro, i wasnt sure but the Version number didnt match the Basic Limewire version i was using, it seemed too new, After that every time i re-installed Limewire it just wouldnt work, i can do a Virus scan, but it usually picks up things anyway, without my doing anything.
