Let's find the data.

So now there is no secret where the data files are. You could wipe out the Palm desktop and reinstall that and restore the data files in a flash. Then if that works you export the data. Sorry but I can't write a step by step. I'm only an author of some PalmOS apps so I can symp with you I stop short of step by steps.

Hope that helps.
