Pls. help. Can not open an important MathCad file anymore?

[ptc-6670572]

I have attached a mathcad file (2015).

I have problem with opening the file, when i try to open it, it says: "mathcad application has stopped working", and shut down. I dont know whats wrong with the file, but I dont have any problems with opnening other mathCad files. It is just this one.

Are there someone who can help me?

And can you tell me what I shall not do to end like this again?

I have just tried opening in M15 with the same result.

Try the attached - there was a corrupted xml statement in Section 5 on page 4, which appears to have a variable missing - I've amended it to read "problemOccursHere" but I suspect there may be data missing as well.

Thank you very much mr. You have saved my day

No worries.

There was a corrupt region (wrong XML end tag) in the file (region-id="2773") which corresponded to an empty region in chapter 5 near the single tau. I corrected the XML code and replaced the empty content by three question marks.

If Mathcad created that wrong code while saving the file, thats a bug.

And it sure is a bug in MC15 (and below?) when we get that .NET system error instead of a correct error message from the Mathcad XML parser.

EDIT: Just noticed that Stuart had beaten me by half an hour.
