Isis black and gold, please Help !

[Fred]

Hello all !
My name is Fred, I am relatively new to the isis adventure.
I own a black and gold Isis with G2 lock, and I'm stuck ....
I easily deciphered the clues, I unlocked the 3rd BB but now I can't find my way to the halfway stage.
I tried what it is said with the clues again and again and again but ... Nothing
Could you please help me in the progress !
Thank you
Fred
