Downloads have wrong file name

[wal355]

on the website http://www.piriform.com

the filename ist always "downloadfile" without a file extension
if I rename the file, respectively give it the correct extension zip or exe it's no problem

problem persits since I'm using FlashGot with firefox integrated dlm

thanks for your information
