Problem:
I got a problem updating the license for vxdiag vcx se Benz doip scanner.
Error 1
Update license Failed. Error 4001
There was an error communicating with the server.
Error 2:
Update License Failed. Unknown error.
Vxdiagshop.com solution:
Always update the firmware first, then update license. Fits all vcx se, vcx nano and vcx plus scanners.
