I agree with Abdu.
Please tell us every file and folder that exists in your x:\Users\\AppData\Roaming\Electrum folder (where x is your system drive and is your windows username)
Then also tell us every file that exists in the "wallets" folder within the above folder.
If you can, maybe take a screenshot, we can see what you are dealing with.
This doesn't look too good... but if you have another wallet file or copy of the file... perhaps it's there...?
