Hi, please stop Maxisys App,  then go to ES File Explorer – Home – Scan – Data Base and delete the masdas.db and masdas.db-journal files. Restart the tool and try to load all the vehicle software.

 I am having this same issue now. I tried to update MaxisysPro "BENZ MAYBACH" v7.00 dated 1/27/2016.

Update could not be completed instead keeps restarting. Then I noticed that I no longer have access to the mercedez benz app. When I click my vehicle history for benz, I get "Library Not Found". Whats going on? How can I restore to my previous setting?

Please help.

 If I remember well once I had same problems and the software which I updated was not matching with the system software..........So, try deleting all the last software you have updated and see if rest of the softwares are working or not or, you can also try other car software and see if those are working or not...............

Hi, some file may be missing during the process of updating. Please uninstall the software and download it again to check the result. If there is still problem, please write to support@autel.com for quick reply. Thanks!
