I still thinking that my wallet is corrupted. The file seems damage. Like i said i always had a possibility to restore an old version of my wallet.
What do you mean you "always had a possibility to restore an old version" of the wallet?

Do you mean you were able to restore old versions of wallets when you were using a different wallet application? (like Bitcoin Core etc)
Here I can't or maybe there is a way to restore the old file with the previous password ?
It's pretty simple... you either have a backup of the old file with the previous password... or you don't. Do you have a copy of that file stored someone like on a usb drive or other backup media? If not, then there is no way for you to magically restore this file
I'm still confused by a comment you made earlier where you said:
3 / I know that's strange for my seed. I try to swith servers, i try everything and nothing works... And I'm sure about the seed because like i said, i recover one of the btc adress. It's green on the corner everytime.
If your seed was recreating a wallet that has the same address that you previously had... then there is something else that isn't working right.
I found someone to buy my wallet for 2 btc... I don't know if i can accept.
If the amount that is in your wallet is even close to 2 BTC... sell it! why is this even a question?

And if you do sell, just remember to use an Escrow service!
I'm guessing your wallets has more than 2 BTC in it?
1 / In Windows , i can restore old version of the file : "properties , previous version" for all my wallet except this one.
2 / No it was my mistake. I write the password and the seed everywhere but i don't think to make a wallet copy.
3 / No my seed WORKS. I recover a wallet with no balance, no adress. NOTHING ON IT.
4 / 2.5 btc on it. But i can forget selling it. The buyer ask me to send it first with no escrow...
So now, i wanna just know who is fault ? Mine, the software , my hard drive ? Becasue i wrote the password, i wrote the seed who recover an empty wallet...
I will never use Electrum again.
@ncsupanda I'm ready to accept your help, maybe you will able to make better passwordlist that i do.
I hope in future someone will find a way to crack electrum wallet...I keep it , hoping that it will be true one day.
