I have had limewire downloaded before and everything worked great, but my dad had to redo everything on the computer so it uninstalled well i am trying to install again and when i click the setup thing it says "The installer you are trying to use is corrupted or incomplete. This could be the result of a damaged disk, a failed download or a virus. You may want to contact the author of this installer to obtain a new copy. It may be possiable to skip this check using the /NCRC command line switch (NOT RECOMMENDED)..... Now what that mean?
