Is Armory fully synced? How many blocks does it say in the bottom right hand corner? Is Bitcoin Core fully synced?
You might be onto something there. At the time I posted this, Armory was showing "Connected (351223 blocks)"
I'm looking into Bitcoin Core now to see how many blocks it loads.
If it is a restored wallet and it was used before you might also to pre generate some addresses so armory could find it.
It is a restored wallet because I has some issues with getting the previous version of Armory to sync at all. However, I haven't actually unlocked the wallet since creating it.
Like an idiot, I sent my BTC to the generated Armory wallet before I understood how Armory works and before I got it installed and online. So now it appears not to have syned up to the latest block, and my passphrase isn't working for my backed up wallet.
Goatpig mentioned there was a tool for brute forcing the passphrase? Is anyone able to talk me through how to use that? I have a 6-word passphrase saved already (copy/paste from the initial wallet setup) so I could use that as a starting point for brute forcing it.
