My NIS has DISAPPEARED!

I too had internet access issues after installing my NIS in the fall however, now my NIS has DISAPPEARED!  I did not uninstall it and I cannot seem to reinstall it from the website!  I am working on a computer with NO security and cannot seem to find a solution online.  HELP
