Hi!!

I have a bitcoin-qt 0.8.6 and some small amount of bitcoins in it

When I try to send them to other address I get a failed transaction

I verified my addresses with listunspent but there is nothing strange

So, I tried to see private keys and ups:

Private key for address 1drau5TSfhkJF4Lo8xdTidwVMFX8HdKp7 is not known (code -4)

I know that I have generated this vanity address and imported the private key to bitcoint-qt

I see the transactions and amount of bitcoins is correct

Can you help?

Cheers, Tom
