Hello All
Recently I have been working on my mathcad file which include formulas and some pictures and it worked fine for a while. I was able to close it every single day and open the file next day. But today I cannot open the file. The application I have on my system is PTC mathcad prime 3 and I havnot updated or change it since I installed it on my machine. I'm able to open other mathcad files but not this file. The log file says:
Exception data:
File being opened: C:\.....\Desktop\MyCalculation.mcdx
FileFormatException when processing file
System.IO.FileFormatException: File contains corrupted data.

I have attached the mathcad and log file. Can you please help me?
