These two errors on a Palm device mean that ListPro is missing some of the databases required for operation.

If you get this error while creating a new list on your Palm:

Re-install ListPro on your Palm to ensure all of the templates are installed.

If you get this error while syncing, or trying to open a list on your Palm:

Create a folder on the Palm and then move the lists that are giving you a problem into that folder. Then, delete the folder and this should solve the problem.
