save project schedule is previous version - Project won't open the file

[thomasbmack]

Yesterday I saved a project schedule (using File, Save), and now when I try to open the file, Project is saying the file was saved in a version prior to Microsoft Project 2000.  Not sure how this happened but is there any way to recover the file?   I used an organization approved license of Project and have no way to load an earlier version of Project to open the file (as instructed by the error message from Project).

I was able to find a version of the file from 1 hour previous to the last save and open the file successfully. thus I am good. but still weird.

@Saikumar445   I did not resolve my issue on the latest version of the file. 

I went to the folder the .mpp file was in, right clicked on file, clicked on Versions and I was able to open the previous version of the file and save it as another file. It was saved only 1 hour before the latest version so I only lost one small change that I easily made in the new file.
