Please don't GET SO HOT !!!!!
I have yet to see a crack for JPRO 2019 / 2020 /2021 done properly. First off, you will need a loader that updates the date in the lic.dat file each time program is loaded. Second, you will need to patch/update/replace the databases, not only volvo/mack but also the main one the program uses to check compatibility of bidirectional. Otherwise you will be missing many of the options that normal JPRO 2019/2020/2021 has under bidirectional tests. There is even more to doing this properly such as patching out the other license checks or blocking in internal firewall.
