When I used "importprivkey" and typed the address it says "Invalid private key encoding (code -5)"
I used "importaddress" and the bitcoins showed up in the Watch-Only balances instead of spendable.
You need to get the private keys out of armory. Go to your wallet properties, click "Backup" and then choose the option for "Export key lists". The private keys are the ones labeled "privbase58" (or something like that).
What you are currently doing is importing the addresses, not the private keys.
