Corrupt File

Hello,

I am getting an error message that says "The docfile has been corrupted" when i try to open this one mathmacd file. I am using Mathcad, version 14.0.0.163.

I'll click okay and when I try to open it again it says "An unknown runtime error ocurred. Exiting..."

Please let me know if you guys can help me open this file.

Thank you in advance
