Contacts won't sync since upgrading to OS 10.5.5

Question

I went about 6 months without using my Palm Z22 (got busy!).  In the meantime, I upgraded by Operating System to 10.5.5.  Don't know whether it's related, but now the personal contacts I entered into my Palm Desktop won't sync to my Z22.  When I sync, it's attempting to sync with a huge database (called Now Contact) that I use in my homebased business.  Before it can finish, it gives me an error and says Syncing wasn't completed.  I don't want it to sync with Now Contact.  I want it to do like before - just sync with the personal contacts in the Addresses section of my Palm Desktop.  Anyone know what I can try?  How do I turn that off?

Here are copies of the "syncs" I tried today.  I realized after my original post that it also won't sync my Palm Desktop Date Book.  It's trying to read Now Up-to-Date from my desktop which is not a calendar application that I even use.   Thanks!

A conflict in the installed conduits has been detected. This is caused when more than one conduit is using the same PIM data type (e.g., Address Book vs. Contacts). To allow synchronization to proceed, use the Conduit Settings dialog to turn off the extra conduits for this user, or drag the extra conduits to the Disabled Conduits folder. 
The following conduits are in conflict:
Now Contact
Contacts
The following conduits are in conflict:
Now Up-to-Date
Calendar

Conduit Conflict Notifier halted the HotSync operation during the <Sync OK> notification.
