Hi, We're having trouble getting the Bulk Operation feature in the web interface to accept a .txt file with rougly 55,000 email addresses to be added to a list. The web interface keeps saying: "The file your browser uploaded looks like a binary file. This function requires a plain text file and will not work with word processor documents, spreadsheets or the like." Yet this file is a .txt file, created in WordPad with all formatting stripped and each email address on a single line. We've never had a problem with this before. Any ideas? Thanks, --Michael
