If you want Pro yes. But you can always use the free version. http://www.limewire.com/english/content/download.shtml
But if you buy pro you can always backup the installer onto an external device just in case something similar happens or you need to reformat for any reason.

Thanks. You seem to know a hell of a lot more than I do about these things. Maybe you could help me with something else. I have recently installed a DVD Rewriter, and although I can play DVDs on it, each time I download a movie from LW, and then click the "Burn" button, the drive then opens, and a message appears saying: Please insert a blank CD in CD Drive. Each time, I always make sure there is a new DVD in, but each time, I always get the same message. Because of this, I must watch my movies on the computer, from the Shared Files. I download movies because I am in Germany, and dont understand German TV, but would just like to watch them from my DVD player in comfort, instead of sitting at the PC. Any ideas where I`m going wrong?
Tony.
