There seems to be a problem with the FTP server on this site

 More specifically, for the OrCad downloads page. I'm attempting to download the Capture and PSpice Demo package, but when I try to download with Firefox, it is unable to determine the size of the file and I eventually get an error, and when I try to connect with an FTP client, it says that the file cannot be found. Is this problem on my end, or the Cadence website's end?
