I'm trying to join the pooled proof of stake. My commands: ./dcrd -u user -P pass ./dcrwallet --create ./dcrwallet -u user -P pass --walletpass=walletpass --dcrdusername=user --dcrdpassword=pass /dcrctl -u user -P pass --wallet getnewaddress /dcrctl -u user -P pass --wallet validateaddress theAddressReturned ./dcrctl -u user -P pass --wallet importscript scriptCopiedFromWebsite -4: address manager is locked where user and password are my username and password. walletpass is my wallet's password. I also have a public passphrase for the wallet. What does "-4: address manager is locked" mean? I guess it's some kind of a failure but I can't see what I'm doing wrong.
