You could add up to 20 addresses (13-14 more?), it takes a minute or so, or
-
You could try another instance of Counterwallet (e.g. from CoinDaddy), or
-
You could use this utility to list the private key for the address and then sweep that address from Counterwallet (to “move” whatever is on it to another address that does show in your Counterwallet)
Is it possible to create list of addresses and private keys from Counterwallet pass phrase?
