Will Shadow work in Palm OS5? Clie TJ25 or TH55?

Hi, gave up a while back when things got very quiet here but I see activity again.

I have registered both PDA and MacOSX Shadow, and have data going back many years.  I used it on a Clie SJ30 (Palm OS4) -- that has finally died.  I've never been able to get Shadow to work on my other Clies, which are Palm OS 5 (TJ25 and TH55).

Should it work?  Any ideas welcome, or pointers if this has been discussed.
