Have one sdc4 DAS Xentry software preinstalled on Lenovo X220. One question is ” Do I have to enter a fixed expiration date ?” Do I need to reinstall the software? The answer is yes, usually enter to 2022 year.
First comes with some images one user shared:
obd2shop.co.uk solution:
Delete all of the above files
Reactivate.
This file “lic_key_2.dat” will automatically appear after you activate, please copy and paste this file, rename the “.dat” as “.x4711”, and change the file properties as “Read-only”.
And also check if the EPC you entered is wrong, or the ID is wrong.
