Photos not syncing after upgrading from Photoshop Elements 5 to 6

Question

Since uprgading from PE 5 to PE 6 all changes I have made to my photo catalog have not been synced to my IPod 30GB.
I have a PC laptop using Win XP Pro which is always kept up-to-date automatically from Microsoft. All worked fine before the uprade to Photoshop Elements. Every time I added photos, or changed some, the next time I plugged the IPod in it would sync the changes to the IPod, but not now.
Any ideas??

Unfortunately, the Sam proposition can't work because PSE 6 as changed the catalog format from MS Access to a another DB : SQLite (http://www.sqlite.org). Triying to change values in Regedit ist just useless.
I've triying myself to copy, and rename, the new PSE 6 catalog file from :
C:\ProgramData\Adobe\Photoshop Elements\Catalogs\[cat name]\My catalog.psedb
to
C:\ProgramData\Adobe\Catalogues\My catalog.psa
With no success.
As stated by Sam, iTunes look for the catalog file located in the following Key :
[HKEYCURRENTUSER\Software\Adobe\Photoshop Elements\5.0\Organizer]
"CurrentDatabaseName"="My Catalog.psa".
In Fine, there is no (simple) solution until Apple decide to make iTunes "PSE 6 compatible".
In fact, the simplest way to transfer photo is to Export photos from the Album in a directory and then synchronize with iTunes from this Directory.
Key and path are for Vista...
