I desperately need a download of the original wallet? I have another support thread (presumably in the wrong place) which expresses I had previously backed up my wallet, recorded the seed key. I even had a few other test wallets/seeds which all have 0 balance. Then I upgraded to new Brave, somehow the original seed must of worked since my balance was successfully imported into the new browser.
I did not backup the latest version, which I still am struggling with; why that would suddenly change your seed keys? Terrible consequences. Anyway, I tried to restore from the older browser backup seed to the new one and they all say 0 BAT imported. So I have lost all my BAT?
