Analysis problem?

I have just updated my Analysis. I have recompiled my WebService and installed that on my server.

I have also updated the webservice in my local app to pick up the changes on the server.

However when I run my app and perform an HModify within the webservice I get:

The <CaseHistory> file is more recent than its description in the analysis.

How on earth, when I feel I have updated everything to be in sync with the analysis changes can a description of a file be more recent than the analysis?

What am I missing?

Thx.
