I had an issue where it appears to have transferred to the Pro20Data folder but they did not show up in the HomeBase view.  Are the transferred clients in the Data folder(Your data computer\pronet\pronet20\20Data)?  If so I was able to get them in the Homebase view by copying them to another location, then deleting them from the Data folder and doing a restore from the copied location back to the data location via File -> Client File Maintenance -> Restore
