This is hands down the BEST media downloader out there. If you are having problems, chances are others have experienced the same thing so be sure to check out the forums. It is very likely that the creator of the add-on will help you directly! Of the issues I've read on the forum, most have been related to user error or just not understanding what is really going on. As a user of computers for over 40 years, I highly recommend this very useful and safe program.
