FYI, I suspect they don't actually deactivate it after 45 days. I think the only way they deactivate is if you use more than 3 computers. Out of curiosity, I checked my TBR FLs online after reading this thread and found that they could still be accessed (even though I ordered them early January).So I think the point of the '45' day thing is so that people focus and set goals for test day. AKA they won't screw you over if you reschedule the mcat or something.
