To work around this problem, convert .mpp files for use in Microsoft Project 98, Microsoft Project 2000, Microsoft Project 2002, and Microsoft Office Project 2003. To do this, use one of the following methods, as appropriate.Method 1: Convert .mpp File from Microsoft Project 4.x for use in Microsoft Project 2000

Open the .mpp file in Microsoft Project 98.
On the File menu, click Save As.
In the File name box, type the file name that you want to save.
In the Save as type list, click Project.
Click Save.

You can now open the file in Microsoft Project 2000.Method 2: Convert an .mpp file to MPX 4.0 formatWith this workaround, you can convert an .mpp file from Microsoft Project 3.x for use in Microsoft Project 98, Microsoft Project 2000, Microsoft Project 2002, or Project 2003. You can also convert an .mpp file from Microsoft Project 4.x for use in Microsoft Project 2000. To do this, follow these steps:

Open the .mpp file in Microsoft Project 4.x.
On the File menu, click Save As.
In the File name box, type the file name that you want to save.
In the Save as type list, click MPX(4.0).
Click Save.

Files in MPX 4.0 format can be opened directly in either Microsoft Project 98 or in Microsoft Project 2000.

I don't think there is anything that can be done to recover it if the file can't be opened. If you do manage to open it, immediately save it as an .xml file (File, Save as, File type xml) then re-open from xml and save as .mpp again. As xml is a text format, any binary corruption should get left behind.
