Centro won't Hotsync Calendar and Contacts with desktop

Question

Here's my problem.  I hotsync, but my Calendar and Contacts don't transfer to or from the handheld to the desktop.  I'm using a Palm Centro and trying to sync with Palm Desktop 4.2.1 on a MacBook running MacOS 10.4.11.
I already tried a complete restart of my Centro, erasing all user data.  I then hotsynced it and it restored from the backup on my MacBook, but this did not fix the problem.  It restored my contacts and all my apps to their prior status, but I lost all the Calendar data in my Centro.  I still have the data on the MacBook from whenever it was just before it stopped synching correctly.
The log proposes that I run the Contacts and Calendar applications and then run a hotsync.  I did that, but no results.  I still get the same stuff in the log.
Please help.

This may be dumb, but I did not think to look for this until i called Palm for help...
After I had issues syncing, I re-installed the Palm software..when you do that, it sometimes turns off the ability to sync. To confirm that you have the ability to sync,  open Palm Desktop and go to Hotsync --> Setup, and check the HotSync Controls to see if it is "Enabled"
Also, if you have problems syncing with Entourage...try this...
