Mathcad stops working when opening certain files

[fward-2]

Dear All,

I was working quite happily in a Mathcad sheet, and went to open an earlier version of the same sheet at which point MC 'stopped working'.  Now, whenever I try to open either of these files, or a file that has them as references, Mathcad 'stops working'  It does however open other files.  I assume that these two files have become damaged or corrupted, but would really like not to lose them.  Does anyone have any solutions for recovering these?

Thanks

Frank

Please find edited Mathcad worksheet in attachment. Also, determine the built-in variable "ORIGIN" in your document. What version of Mathcad are you use?

And what service release of Mathcad (in main menu select: "Help" --> "About Mathcad")?

[fward-2]

Mathcad 15.0 (M030 [MC15_M030_20131216])

Frank,

Is there any chance for you to update your version up to the latest Mathcad 15 M045 service release?

Hi Frank,

You must place the variable ORIGIN  = 0. Currently in the file it is set to 1, so it gives the first mistake. Furthermore , it follows that the  index of Nom is 1, n + 6 and so on.
