Ok, it is properly creating the export .csv file, and I can download it manually via ftp. If I left click the "Download" link I get a 500 error, and if I right click the Download link and do a "save as" the file is filled with the same 500 error. So, I believe it has something to do with adding the proper permissions in my .htaccess file, in the temp directory. I read something in the instructions about adding "allow" in my .htaccess file for .txt and .csv files, but I'm not sure what code I need to add to my .htaccess file to accomplish this.

Thanks!
