Problems opening a Mathcad Prime 3.0 File

I was trying to do some basic calculations for the cooling cycle. Multiplication/addition/division/etc. with some variables I set. Turned off computer and when I went back to continue I get this error:

The file type is not supported.

Log file is located at: c:\ProgramData\PTC\Mathcad Prime\Logs\Mathcad Prime_Exception_20150407_164625.log

I was wondering if there is any way to get back at the file without having to start over from the beginning. Attached is the mathcad file I was attempting to open and the Log file referenced in the error.
