From a note in the guide:
Upload all files (including the Modules subfolder) in the cgi-bin folder of the zip file into your cgi directory. Permissions for all of these files and your cgi directory must be set to 755. You do not need to set permissions on the Modules subfolder or its contents.
As memory calls I remember it is more steps for permission settings for classic. So you need to double check all of the file/folder permissions.
Also you need to make sure you use ascii for the proper file uploads.
