Toolbox custom properties gone haywire!

Alrighty, a good place to start would be to detail some background
before describing the problem. I will also go into the details that
probably aided this problem. (This is also posted on the SolidWorks
forum, sorry if you read this twice).

Background
All the toolbox parts what we use have three custom properties (CPs)
that we created. There is Our P/N, Manuf. P/N, and Description. We've
been using these custom properties for about 2 years without much
problem. We're using SolidWorks 2007 Professional.

The Culprit?
I updated us to SP4.0 (SW2007) from SP3.0 or SP3.1. I was thrilled to
find that this erased all files on my server's root folder. Several
days later my engineers informed me that the toolbox was messed up. I
checked the custom properties of several specific parts (after rolling
my eyes of course) and discovered that they were correct, something
fishy was up with our toolbox!

Problem
I had previously mentioned that we have 3 CPs for each configuration
that we use. Now for some parts we only had two; "Description" was
missing completely. Furthermore, some of my CPs had changed to the CPs
of other parts. For example, my 0.25" regular lock washer lists the P/
N and Manuf. P/N of my 0.5" regular lock washer. Description was still
missing, of course.

Plea
Anyone who has seen similar funked behavior please let me know how you
fixed it! I'd rather gnaw my arm off before telling my engineers they
have to redo all these CPs, which would result in me watching them
gnaw their arms off to avoid doing the same thing twice.

Thanks!
The Mex
