Microsoft Project does not open; Even after enabling the project from Options -> Addins -> enable the Disabled file in the Manage options.

Dear experts

I have two issues for which I seek help.

1. My Microsoft project does not open, hangs, no matter how many times I disable the Options -> Addins -> enable the Disabled file in the Manage options.

I also copied the file and tried. It has no previous versions. Any advice

I plan to open this in 2013 version of Project later but I really need your advice.

Regards
