End note has changed all my references, How to fix it?

Hi , I am writing my thesis and in final stage of editing I realized that Endnote has changed all the references in the whole thesis. Following is a sample of what has happened:

Correct (older) VERSION:

… sign expectation(Kennedy, 2005). In an example in (Rao and Mille, 1971) the …

NEW VERSION (same file after corrections and couple of revisions ):

… sign expectation(Kennedy, 2003). In an example in (Kennedy, 2005) the output of a …

It is pretty much like this in the whole text without any recognisable pattern.

I was using X2 version then upgraded to X2.4 and again changed it to X3 but the problem is still there .

Does anybody know what is the reason and how can I fix it?

Your help is much appreciated.

Thanks,

Reza

The following FAQ may help, but given the example you provided it may not:

If the document cannot be corrected with the previous FAQ you would need to use the steps in this FAQ:

After the document is unformatted and pasted into a new document you would need to correct any of the citations that are displaying the incorrect reference.
