Not sure if your issues match my past issues but perhaps the observations and adjustments made will help you. Key focus areas are your Autel ID and Autel Community User Name. PC suite installation CD that came with my MD802 was slightly less refined than current versions. My version cut off part of my Autel ID name and made it unrecognizable. Resolution for truncating issue was found on Autel forum  www.dropbox.com/s/hm50yn2qrt9qgxa/setup_Autel_PC_Suit%20v3.0.exe 
 
Next issue was tied to file name conflicts of my PC. Autel Community User Name and serial number file names had to be adjusted to match my device. Note that your new Autel Community User Name has to match your profile on Autel's registration page.

Good luck. 

Right now you need a PC SUIT V6.13 , which can be downloaded in your account when you logged in our site.

 i tacked this on to this thread rather than start one because of the warning about matching autel and community ID's as mentioned above.

i have had constant without success once of download failure.
my autel ID is my email address, and i cant edit that, and my community ID will not accept the @ when i try to set it to my email.
i have checked my connection thoughly. it is working ok.
any ideas ?
