My MD805 was working great until upgrade. Now it stalls and displays “The vehicle program is not authorized Please obtain authorization!”.
I have tried so many suggested solutions but nothing has worked. Even emailed the company in China, who offered assistance, but no help.
I looked into the card and found the file, authorization.txt, was written in code, not good.
I have little time left before the tool must be returned, just need the password to rewrite a new card.
Machine is MD805 serial number ME5818000459. Please help
