The problem is that i know my password.. This is bug with wallet.. i wrote my pass on the paper as well and im using it for a while, so there is no way that i dont know my pwd...
If it is a problem with wallet and if you are secure to know your password try with gdbix (command line wallet) with this command:
start gbix
after sync open new shell with "gdbix attach" (without close gbix in other shell)
in console write:
to see your balace
web3.fromWei(eth.getBalance(eth.coinbase),"ether")
to unlock wallet
personal.unlockAccount(eth.accounts[0], 'your.wallet.password', seconds)
(dont delete ' ' and change "seconds" with number this is the time when the wallet will remain unlocked)
now is possible sent tx
eth.sendTransaction({from: eth.coinbase, to: "0xADDRESSRECEIVING", value: web3.toWei(123456, "ether")})
(change 123456 with your dbix amount to send)
