Directory Plugin and uploading CSV database files

Are there ANY directions on how to upload a .csv file that includes which uploader works best for Directory. I've spent hours and hours trying to get Ultimate CSV Importer to work and have been unable to. Custom fields aren't appearing and information is not propagating into the directory. This plugin is suppose to be powerful and easy to set up "under 30 minutes" and it is anything but that. I subscribed to WPMUDEV in order to get help with anything I need and I cannot get the help I need. How do you suggest I get this plugin working as soon as possible so that I do not lose additional time and money?
