Thanks for that but that brain key just creates another wallet, without my account in there.

I can get into and unlock that wallet fine but my account - bitsharesjohn123 is not there. Although it does show under 'Ignored accounts', below the other accounts I've made.

I have a password for it but I cannot enter this anywhere.

What i think i've done is not backed up the first wallet and account i made, then in a confused state made a new wallet with the same password as the account i set up in the first wallet, and then backed up that.

My own fault, funds to the BTS gods.
