Mathcad 4 prime file recovery, HELP

[RG_Ace]

Hi

someone could help me to recover my mathcad 4 file, every time I open it this message appears.

I would be very grateful if someone would help me recover my file, I have invested many hours in it.

Sorry, the file is lost. The .mcdx file enclosed in the .ZIP archive contains 6 904 424 bytes, which are all 0. This means there is no other information that this file provides other than its size.This also explains why the .ZIP archive is so small.

I hope you have a backup.

Success!
Luc

Your files consists just of all identical zero bytes. There is no information which could be recovered.

I hope you have a backup that you can fall back on.
