CoursePress with New Blog Templates

I have the most updated version of WordPress, New Blog Template, and CoursePress plugins in my site http://foxybuilder.com/, it's multisite.
But when I register a site using CoursePress template, it's giving
" insertion Error: Can't write; duplicate key in table 'wp_185_wc_download_log' - The template was not applied. (New Blog Templates - With CREATE TABLE query for Additional Tables) "
How can we resolve this problem?
