I've inspected the .MCDX file. The file structure is damaged. But I can see it contains a worksheet and several pictures. The pictures can be recovered, such as:

image28.jpg

But I suspect not all of them are stored, part of them may be in the corrupted section. I suppose/hope you have them available elsewhere.

I've recovered the worksheet, but the relations to the pictures as well as the text surrounding your equations is lost. I think you should be able to recreate the full worksheet with the help of the attached sheet (Prime 6).

 

Success!

The LOG file is of little to no use. Attach the (corrupt) Prime worksheet file. From there it may be possible to recover part of it.

 

Success!

Dear LucMeekes,

 

Thanks for your reply.

As requested, the corrupted file is attached.

Thanks Mr. LucMeekes.

 

That is really helpful.

I have the pictures and I can rewrite the text.

 

Warm Regards.
