If you are trying to download the whole video through the link to the 'basic' video file that you reeived in your email receipt, the zip file will be quite large (3 hours of HD video).
If you have a bandwidth limited 'net connection, you are better off downloading the individual videos over time to the LuLa Player app or perhaps trying to stream through your browser. If you still have problems, I suggest contacting the
Purple help system.
There is currently no alternative to the Purple system - but we are working on that...
