Hello I have been trying to open Mathcad 7 files on the trial version of mathcad 15 and everytime I get the message "Mathcad Application has stopped working". They are crucial files needed for my research so I would appreciate any suggestion on what to do.
I have also tried converting to XMCD to view using Mathcad Prime 3.1 but always gives the message "Unexpected error encountered during conversion"
