Whats the size of the byte if you look at its information with explorer? Does it happen to be 0 bytes?

Does the logfile gives any clue as to what was going on?

In case the file is not zero bytes in length - are you allowed to post it here?

If yes - post it here, if no, try renaming the file to the extension *.zip an see if you can open it with any zip archiver (WinRAR, 7Zip, Winzip, ....)

Unfortunately, based on past experience, the file is probably trashed. Mathcad 15 sometimes corrupts files, but more often then not is does so in a way that most of the file is recoverable. When Prime corrupts a file it often fills the entire file with NULL characters, so there's nothing to recover. If you can, post the file here.

"If you can, post the file here."

That is: you post the Prime file (the one with extension .mcdx), not the .log file.

Hello!

Mathcad suddenly crashed with the file I last saved 1,5 h ago (not very well done, I know).

When I try to post you the file here, this appears:
 

The contents of the attachment doesn't match its file type.

 

Is there any way I could get the file recovered?

Put the Mathcad file in a compressed (zip) folder, then you can upload it.  This forum doesn't like Mathcad files to be uploaded directly.

Try this.  I don't have Prime 4 on my computer, so I can't check if it's working.

Does not successfully open in my Prime 4 express.

That's a bad sign.

The log file complained:

"Exception data:
File being opened: Esimerkkilaskelmat129-20170914_183533.mcdx
Schema validation exception: The 'precision' attribute is invalid - The value '' is invalid according to its datatype 'Union' - The value '' is not valid according to any of the memberTypes of the union."

 

So:

There was an offending parameter in the worksheet.xml file, a couple of times: precision=""

I've set each to: precision="1".

 

Try the attached file (after unzipping the .mcdx file out of it.)

 

Success!
