Hi..... HELP.
I have a corrupted, unrecoverable wallet.dat file.

I can't get any of this working.

Now at the
Instead do that:
It would be easier to install WinPython (choose 32 or 64bit depending on your computer: https://sourceforge.net/projects/winpython/files/WinPython_2.7/2.7.12.4/)
Go where you installed it
Launch "WinPython Command Prompt.exe"
Execute this: python -m pip install twisted ecdsa
Then: python C:\path\to\pywallet.py
Stage.

and I get this:

 File "pywallet.py", line 852
    _p = 0xFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFEFFFFFC2FL
                                                                           ^

I doubt I can get my wallet back as its been overwritten, but undelete software can still locate the old file, but recovery of it leaves a corrupt file.

This seems my only slim chance but I have no idea what I am doing.
PLEASE HELP
