The Serial Number of my MD802 is MD8112006317 and the Register Password is 497778. The tool is over a year old and has not had any software updates. I believe I did register the tool when it was new. I want to update the software now but I am unable to re-register the tool when I log in to My Account, for some reason when I enter the above serial number and password the registration fails so I am unable to progress further into my account to find what updates are available. This also happens when I insert the SD card for the tool directly into my PC. Also, I have the original Autel PC Suite on my PC, installed from the CD that came with the tool when new. How do I install the latest PC suite?
