Problem with Importing from NING

Hi guys,
Love your plugin. I used it on a test site and it worked perfectly for me... it imported over 8500 users. However, I am not done with the site, and i tried 3 times to do the same thing and its not working for me. I am using Buddypress, Custom Community 1.8.9.1 by Themekraft Theme, and members can sign up with no problem. The CSV file is recognized when I FTP, i fill out the email, and initiate importing, but when it says processing, the gravatars dont show up like they did on the test import. Whats different is its a different site and theme... but all the settings are the same. PLEASE HELP!
Thank you
