Error opening a Microsoft Project 2007 file

Question

I am receiving an error when trying to open a Project 2007 file.  There is no error code.  The error says "The operation cannot be completed because the source file contains invalid project data or the total number of rows would exceed the limit
of 1,048,000 rows in a project."

Answer 1

Here's one suggestion
If you can't even open the file you may be out of luck. With Project
active but no projects open, try turning off automatic calculation
(Tools/Options/Calculation tab). You may get lucky and then be able to
open the file. If you can, first look for links on summary lines since
they are the most prominent cause for circular relationships. Remove
links and summary lines and then turn calculation back on. If that
solves the problem, you might be OK. If that doesn't solve the problem,
follow the steps in FAQ 43 - File Bloat? Might be corruption, which you
can find on our MVP website at:
http://project.mvps.org/faqs.htm.
If none of the above works, you might try sorting by Unique ID.
Sometimes an inadvertent keystroke can create a rogue task that is way
out in left field. If there is a blank task name for the highest Unique
ID, then delete that task and see if that helps.

And some more
First I suggest installing SP-1 if you have not already.
Then try method 4 from FAQ 43 at
http://project.mvps.org/faqs.htm. If
you cannot open the file, methods 1,2, and 3 are not available. Method
2 also only works with versions 2003 and earlier.
Neither are a guarantee of course.
You may need to resort to a backup copy of the file.
I hope this helps. Let us know how you get along.
