I think I found the problem. It said that "selected applications" had to have folders associated, but it seems it needed to have folders associated even with the applications I had un-selected (notes and tasks). Now it will synchronize again.
My advice to anyone thinking about trying the wireless synch: DON'T. Great way to waste (yet another) hour on the pearl.
