When try to unzip the files I get a message that many of the files are password protected, but I did'nt get a password with the purchase. There are many files that are now missing from the installation including the promised image based lighting file for P6. Does ANYONE know ANYTHING about this if so PLEASE help me out. The files that seem to be missing are 'Manhattan_Light.lt2' and 'Manhattan_Light'. Winzip tells me that both of these are password protected. Thank you in advance! C.
