Solution from Gm-Tech2.com engineer:
Browse www.dbscar.com website on computer with your X431 account and password to check if you can select your region and language you or not. If cannot select your desire language which indicates that you did not open the region/language authorization, so you fail to update.
NOTE: You MUST open region and language authorization AFTER you received the Launch X431 Pro diagnostic system. then register to download software and run an upgrade.
