Most likely you will see warnings about the Valuesweekly.xml and Valuesdaily.xml file as well. Anyway, it is possible that you have done a setup on a new system (see related question) and forgot to copy the Value-folder from the old to the new system. A second, less likely, possibility is that the e-mails from the mail server were processed in the wrong order. This can happen when the manager is not yet configured to collect mail, and the e-mails from the clients are accumulating on the mail server.
