Did you guys ever solve this issue?


I have had a MCU Pro and a C4 Pro running beautifully... So I decided to buy an XT Pro. Got it today, cant get it to work, keep getting the "security unlock failed - shutting down" message when Logic starts. Not much info online about this either.


Please give me some tips if you worked thru this. Thanks!
