I didn't stop the creaking, the creaking stopped me. I discovered what i think was the problem when i went to clean the cranks.
Removed the non drive crank, gave the axle a gentle tap to get the drive side to move and the bottom bracket cup came out attached to the crank. The threads on the Hope cup were minimal, and with the damaged frame threads there simply was no purchase. I got a newer bottom bracket with a better thread, it seems to have had enough thread to tighten. Tightened it up and it seems to have worked, no more creaking. It isn't held in by many threads though. I would consider getting a saint bb as the cups are longer if i was keeping the bike, which i am not.
