I have a rather big plan of the project I'm working in 2013 within a few months. about a week ago, everything was fine. Now, when I tried to open .mpp from the file Manager or the "recently opened files", project (program) opens, but to open your .mpp. When I try to just open the program and then manually navigating to the folder where my .mpp is located and discover it's been that way, this project actually stops responding.

I can open a new empty project, everything works fine, so I think my file was corrupted. I've read a few things that could potentially help, as the restoration project, restoring previous versions and delete all the links / predecessors from the plan, but they don't help. Who knows the answer what it is...
Thanks in advance!!
