I've setup two links so you can try yourself and see if you get the same
result

The first is link from the webpage
http://www.powerfront.net/secure/downloadfile.asp?fileid=1001959&referid=1001960

cut and paste the following into your web browser (i've added pass=1 to
bypass the html weblink response)
http://www.powerfront.net/secure/downloadfile.asp?fileid=1001959&referid=1001960&pass=1
