      • what happened if i click register before run dc unlocker?..
        i click register and it says thanks for registration, but i clicked before open dc unlocker, and it didnt showed me the flashing proccess, is that mean i have to register it again with another registration key??

  1. Sir, there is something wrong with your software, when i enter name and key from you into the software, the CMD display will immediately close. then when i open the software again and enter the name and key earlier, the display “your registration information is incorrect” will appear. after i read in the comments box that this incident not only happened to me, but people reported the same thing in the comments box. so please fix and repair the software. Thanks
