Master Password Key Found! Power down stopped

Good news - after much searching around, I finally found a scrap of paper with references to the "S-word" and my handwritten scrawls. They looked like possible keys...

After multiple attempts - to follow my own handwriting (!) - I successfully changed my recovery account to @hive.recovery using the excellent instructions from @arcange.

Not only is it a relief to have shifted my 'trusted' account recovery account away from the "S-word", but this process also confirmed that I have found my Master password key (as this what was missing previously when I first attempted to change recovery accounts and that led to my reluctant power down with a view to transferring my stake and starting again with a new account).

This breakthrough means that there's no longer a need to transfer my account, and so I have cancelled my powerdown and powered up the first tranche of my stake that had been released (after the first week).

I am relieved not to have to start again so it's back to business as normal. Thanks to the team at @peakd for their advice and assistance when I first posted that I thought I would have to power down.
