After some hours of fiddling, I found a go around to make this work. Browsing through many of the threads on this topic, I couldn't get any of the advice to work, but this does . . .
I had a Treo 700p and just got a BB 8830
1. Export from Palm Desktop whatever data you want transferred (i.e. address book) as a comma separated text file (.csv)
2. Then, completely remove your current Palm Desktop software from your computer.
3. Go to Palm.com and download version 4.0.1 and install it.
4. Import the csv files into your new Palm Desktop program (version 4.0.1)
5. Now, do the Swith Device Wizard through the Blackberry Desktop Manager.
DONE!
Hope this saves some other poor soul a few hours of frustration.
