I have a pretty big project plan I'm working on in 2013 for a few
months'. about a week ago, everything was fine. Now that I've tried
discover. mpp from file Manager or " recently opened files",
project (s) opens, but does not open its own .mpp. When I try to just
open the program and then manually go to the folder where my .mpp is located and
open it this way, the project actually stops responding
requests.

I can open a new empty project, everything is there
it works fine, so I think my file has become corrupted. I read
a few things that could potentially help, as the restoration
project, restore previous versions and remove all references /
predecessors from the plan, but they don't help. Who knows the answer what it is…
Advance thanks!!

Hi,

have you uninstalled / reinstalled Microsoft Project on either the same system or in a different one?

Hello , try to restore from a backup , or you can write to microsoft support . if you do not have any other way to help , you can try to use the service eRepair SQL Server - http://www.erepairsqlserver.com/
