What wallet you use exactly? Has your wallet option to export private keys of all your Ethereum addresses from that wallet and use them on another wallet and send your coins? Is by the way your wallet password protected and this not allow you to send coins?
I say it already i use "Ethereum wallet for Windows" Yes i have private keys and i dont have to export them since they are in AppData/Roaming/Ethereum/keystore... But these keys are for parrent address of contract address where my coins are... With Metamask, MyEtherWallet, etc... i can send coins only from base address, not from contract address... I also have password but it is not a problem at all
