All ePublisher Express projects should be synchronized with Stationery any time the Stationery designer modifies the Stationery. ePublisher Express projects must be synchronized with the Stationery in order for ePublisher to include the changes made by the Stationery designer to the Stationery file in an ePublisher Express project. When you synchronize an ePublisher Express project (.wrp file) with Stationery (.wxsp file), ePublisher updates the information in the ePublisher Express project to match the information in the Stationery file. If you choose not to synchronize, your project will retain its old settings and the information in the project file will not match the information in the Stationery file until you synchronize.
