Did you refresh the data area in Logbook Pro if it was open during the sync?
Yes
Did you run through SingleSync and check all the configuration settings since you changed devices?
Yes
You may want to consider using our latest release candidate (in the Logbook Pro 1.10 BETA Forum) as it has a new PDA Wizard that replaces SingleSync and is more powerful and reliable than SingleSync, which we are phasing out with the 1.10 release.
