I created a encrypted system on one machine with a login protector and then moved to another machine. I need to make a new login protector. Meanwhile I created a custom protector to get by. The problem is I can not remove it neither on the new machine nor on the old. I will loose the old machine in a few hours so if it is needed then this is urgent so please help.
