Custom property problem - HALP!

Alrighty, a good place to start would be to detail somebackground before describing the problem. I will also go into thedetails that probably aided this problem.

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

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

Problem
I had previously mentioned that we have 3 CPs for eachconfiguration that we use. Now for some parts we only had two;"Description" was missing completely. Furthermore, some of my CPshad 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" regularlock washer. Description was still missing, of course.

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

Thanks!
