My flash drive is security protected with bit lock

Hello,

My flash drive is security protected with bit locker because i once i put a password and also remove the password and now i cannot remember the password again. since i formatted my system and i cannot use my flash drive and its asking me to type the 48 digits recovery key and i don't have it but i have the identifier 1FEFCF10. But i need the 48 digits recovery key to enable me recover my files on my flash drive. I can't use my flash drive. Please help me to unlock the password or tell me the alternative accessing for me to recover my flash drive.

Thanks and God bless
