note 59112 added to install.problems

I am frustrated! I'm trying to set up osCommerce and I'm getting this initial warning: "Warning: Installation directory exists at: /hsphere/local/home/pambell/ newrevelationpublishers.com/catalog/install. Please remove this directory for security reasons." It also states that "If there are any error or warning messages shown above, please correct them first before proceeding." I don't find any instruction on how to do what it's telling me to do. Everthing I read is programmer jargon and I am not a programmer.
