Hello.
first of all ty very much for your response. if you take a look at the first picture you can see on top of the picture that -0.08 BTC have been subtracted from my account. so 0.07 too much was been substracted from my account altough the blockchain says that only 0.01 have been send. do you know why?
Electrum uses change addresses by default. That means, it always sends all Bitcoin of an address, one to the recipient, the other part to a new address of which you hold the private key.
TryNinja told you what to do:
That's probably your change address. Copy the second address, go to Electrum's console and type: ismine('YOUR ADDRESS')
If this returns true, you have control over the address and these coins are still in your wallet.
