Error message: Internet Explorer (IE) Error Message while opening the EBU Mask

While opening the EBU Mask in Database Manager, an error message "Error during XSLT transformation" appears! Why?
Solution: There's a special file, the "dc_archive.dtd" provided by the EBU. If this file is not located in your EBU-Sound-Folder, it can be that this error message will be displayed. We recommend always installing this file! You can download it here: http://support.davidsystems.com/sis_forum_temp/dbm_ebu/dc_archive.dtd
