Hello Busaman you've mentioned that it just stops randomly and did you finish getting updated to UI version 3.03 before subscription ran out. I've been doing fairly well so far all the read and decode vin were working until today probably 10 to 15 cars 5 or 6 manufacturers in the USA region. Today was working on a 2010 E-150 with fuel trim codes and went to active tests to see if it did a service bay EVAP System for a purge possibly being stuck open and then the screen went blank except for I'll call it a task bar on the bottom remained. Reboot and re-entered got maxisys stopped working (what else is new). Figuring typical Autel hit and miss diagnostics tried final time and was able to continue working (hurrah). Yours showing any of this or exactly how does scanner stop just curious.
