The MB SD C4 i bought can not save the xentry data, each time i need to reactivate it and then paste the code again, it is too much time-costing.
i chat with chinacardiags.com online services, chat with seven, and she helped me to solve the problem.
Just share with you.
Firstly: find the directory: C:ProgramData/LicDir and then delete the other files except:
only keep the three files,
and secondly activate the xentry by yourself with keygen or send to seller’s Email: email@example.com to get activation code to activate it.
thirdly: go to C:ProgramData/LicDir and find the data lic_key_2.dat, copy it and paste it, and then rename the file to lic_key_2.x4711.
and then click it yes. and right click it and make it as read only.
