I have purchased Developing Modular Rigging Systems with Python few days back. I have received the link to download it. I downloaded Part2.ZIP successfully, but could not download the Part1.ZIP, I have tried so many times but I get an error.

I emailed regarding this problem at info@3dbuzz.com but haven't received any reply. Could you please help me out ,else the download link will expire in next few days and I won't be able to download the videos anymore.
