My Fragments Purchase Code won't work...

Hey!

I bought fragments and set it up on my PC and computer and they were working fine until about 20 minutes ago, my PC crashed while editing and when I restarted it, After Effects preferences were reset since I assume the preferences file got corrupted, for some reason, this also reset motion bro and deactivated my purchase code and now I can’t activate it again as its already detecting that its activated on two devices… How can I reset it so that all previous devices are forgotten? Please help.
