Someone here told me to restore a wallet with my seed and i did. Then, to try to recover some btc adress used and i did find two of them.
When i say no balance , no adress, i mean no balance and no History of transactions.

But when i go to "adress", i find two btc adress who i used to move funds.

So we can tell that Electrum restore 2 of my old btc adress , with my seeds.

I hope i'm more clear now. Do i have to stop asking Dave Recovery service ?
