Hmmm, I get the same issue, probably some weird directory permissions error... or something.
To work around this, what I would suggest is that after you get to Step 6. and have all your keys displayed (you might also want make sure that "Include Unused (Address Pool)" is also checked, as your wallet is not synced, so it might think some addresses are unused when they actually contain coins) do the following:
Step 7. click the "copy to clipboard" button and then paste it into a text document.
Alternatively, just highlight all the text in the window and copy/paste the text manually into a text document. You will then have all your private keys and you can import/sweep them into Electrum.
yeah, but as I enter to electrum, lets say I copy/pasted my private keys and everything to notepad file.
Then when I get to select a file to import my keys etc then it says "cannot read the file" so it leads nowhere.
I am now currently again updating blockchain through bitcore and then I try to run armor and maybe , maybe it lead my armor wallet become online again.
Right now I am in bad loop.
I saw my bitcoins once in armory wallet (when blockchain was downloaded and waited hours for it) then i proceeded to withdraw my BTC and I couldn't make a transaction to any address(Can't remember the reason or error, what was prompted).
then I did some research and found out that I am using older version. Went from last version to the latest one and now when I open up Armory, then it doesn't even load the black box , where it said the things, what the program is doing.
((EDIT :: right now as I am writing this, Bitcoin core just said "failed to read from database" and closed itself -.-" ))
