Yahoo! Product Submit Feeder

Hi,

I want to install Yahoo! Product Submit Feeder, but I don't know if I have to create data.txt munally after installing or else. Further, I want to know how to install sql file because I see three update sql files in the folder.

Following is the Add-on file I intend to install:
Zen Cart™ Version: v1.3.8
Version: 1.08a
Last Updated: May 12 2008
Author: Numinix

Thanks for much for your help and thought.

I finally installed Yahoo Feed, but I got this error when uploading Product Feed to Yahoo.

Yahoo! FTP content:Connected to: ftp.productsubmit.adcentral.yahoo.comLogin failed: Username: ftp_username Password: ftp_password

Please tell me why I got this error. Thanks for your help.

I receive this message when trying to upload Product Feed from Zencart Admin:

Please help me with this issue. Thanks so much.
