Went to make a purchase, entered my pin, didn't work, freaked out thought I forgot it, entered the only other numbers I would ever use, now it's locked, and my coins are lost forever. /angry The laptop I used to sign up had a screen shot of the security phrase, but guess what laptops crap out or jump in bathtubs then end up as gun targets, and things pertaining to criminal activity I don't exactly back up and keep a copy of.
