Need help to access tutorial video content

[LauraRose]

Last month ordered the Finger Drumming Tutorial at the time of purchasing the MF3D device, along with soundpacks. Due to the DJTT shop switching, it appears today I am unable to access my order history online to download the tutorial -- no record of my account or order exists (except my email inbox receipt); the account did not transfer with the shop switch, it seems. Also, in the files downloaded there is a .mxf video file under a QWERTY drumming content folder (~4mb) but trying to open and play the file, keep getting errors - content cannot be rendered. Installed/updated KLITE MEGA codecs on the system which should play .MXF. Can't open with VLC Player, Windows Media Player (Win 7 64bit Op Sys), or MPC-HC64.

Want to access - suggestions welcome

UPDATE: Somehow was able to login and order showed back up...hooray...but the link to play the video for the Mad Zach extended tutorial says 404 OOPS error - file not found. Also, still can't open the MXF file after restart.
