Ok, I figured out my amateur mistake and thought I'd post for other newbies.
Steps 4 and 5
4. FTP the contents of [temp directory]/1_Install_Files into the ROOT of your Zen Cart installation (i.e. your "/catalog"folder). The files are already arranged following the Zen Cart folder structure.
5. FTP the contents of [temp directory]/2_Required_Core_Edits into the root of your Zen Cart. installation (i.e. your "/catalog" folder). The files are already arranged following the Zen Cart folder structure.
I uploaded the folders instead of the "contents of the folders" oops.
Thanks for the response.
