I hope the developer will tend to this issue because I really love this coin and I dont want to lose it. I tried your solution but it has no avail. and one more thing, I dont know why SFC qt wallet doesn't have a check balance and repair wallet command?
Regards,

just to make sure,
is this wallet showing the unconfirmed balance?
if you've been moving wallets around, it's the simplest answer that you're trying to dump the key from a wallet that doesnt have that address :p
………….
another fun thing to try … is to send the coins from that address to somewhere else
method 1)
send coins from your old pre-fork client, will only work if it's connected to the network (but obviously not synced),
if succesful, it will still send a valid tx to the network which will work.
method 2)
alternatively,
you can create a tx on the old client, and send it from the new.
the old client does not need to be connected to the network at all for this.
create a transaction that send the coins from the pre-forked client, get the txid,
console
getrawtransaction txidfromabove
copy all that,
start new client,
console
sendrawtransaction alltheblatherthatisarawtransaction
,
sending the coins might work because the transaction really has nothing to do with your wallet per se, but instead it's success depends on the network agreeing with the contents ie whether the transaction is valid or not.
so as long as the transaction is valid, everything will work.
a cold wallet has no need to touch the network, but can be used to create transactions, which are then sent from an online client.
it can create transaction because it holds the correct information (prior transactions and private keys) to formulate valid transactions
so, your old client holds all the correct information to create a valid transaction
