This company is retarded, so I figured I would get this to work myself. If you registered your maxidas years ago on maxidas.com like I did you need to do this to update your machine to 3.16. The company has not correctly merged information from the 2 sites. (username/password/serial.)
If you put the SD card in the comp you will come up with your correct username:
Open the drive that is associated with the card. > scan > update
the top folder name will be your sign in name to the 6.13 update. use your password from the maxidas.com site.
Ur welcome.
P.s. my login was the same as the website but split with extra letters added
