Anti Theft @ My Pc

Hi.


I choose a trial Bitdefender Total Security 2013 before I buy It. Today I try, in my Toshiba Satellite with WIN8, the Anti-Theft. I thought: -"I choose a pin and if someone take my pc away I activate it".


Well...


Now I have the screen of my pc saying "Bitdefender safe lock >" and I've nowhere to insert the pin. The lights of Caps lock and NUM Lock are flashing. I can't do anything with my pc!!!!


With another I joined my bitdefender account but I can't delete the pin or stop the anti theft!!!!


I need to work with my pc tomorrow!!!!´


Please, HELP me :(
