There are spammers touting Project repair software.

Since that's spammed and easy to find with google, let's make this a spam free zone. No links,

As any project manager knows you keep backup copies for when this happens. Sometimes the manager needs to lose it all a few times until they accept that backups are not optional.

I can't guess if you turned on the backup feature. Here's the picture:

PS. Another thing you may notice about the spammers.

They usually join a forum shortly after you posted this question. Let's see if that happens.

Method 1

Method 1 - Because of the way Project stores files, file fragmentation may be the basic cause. To make sure this isn’t the problem: open your .mpp file then select File/Save immediately before doing any other action. Only if you save immediately after opening does Project defragment its .mpp file. If you do not have external links in your file, (i.e. resource pool, master with subprojects, etc.), then a good practice is to always use Save As instead of a straight Save with your file after editing. This helps keep editing clutter from being appended to the file. However, be advised that using Save As with linked files can actually create corruption/bloat due to multiple link paths being created IF the file is not saved back to its original name and path.
Method 3 - Repeat the above steps except for step 3, Save As to .xml.
Method 4 - (Be advised that this will eliminate all custom formatting and that the new blank file created in step 1 should be pre-formatted with custom views, fields, calendars, etc.
(Try using the organizer to import such from the Global .mpt))

Why didn't you just post same answer here?

I fear it's because the app you noted doesn't really work and is just spam.
