Re: I have my wallet.dat from a backup but I can't remember my passphrase
I think we already talked @ Github 
I guess you mean that: extract-electrum-halfseed.py
yep, because "extract-electrum-halfseed.py" and "extract-electrum2-partmpk.py" do not work with encrypted wallets.
you ever used the password after you have changed it? If yes, and it worked - your Wallet-File is probably Corrupt (somehow) - if not, then you probably made an mistake while creating the new password.
my recommendation:
Start with the "Typos", so you can exclude that you have errors with upper/lower letters, swapt letters, missing letters or double letters. (these are usually the most common mistakes)
EDIT: I just see that HCP has already recommended this to you.
Best Regards

And i'm sure that the wallet is from Electrum. I can't understand why my password who i wrote and the seed doesn't work.
There was a bug on my HDD when i changed Electrum version.
