Hello, I just downloaded a tutorial from the video training section and I'm having some issues with the file: 1. On my PC, when I try upzipping the file, I get the following WinZip error: bad CRC 706013fe (should be ee6d1748) 2. On my Mac, it downloads fine, but it only plays 9 minutes of a 29 minute movie (it craps out after 9 minutes). Has anyone ever had this problem? Any suggestions or advise is greatly appreciated!
