Hi Tim, Getting to your second question first: You need something to produce PDF. Editor alone will not do it. Styler, Publishing Engine, Architect, APP, any of these will do. Now, to your first question: There should be no issues sending source files between 5.2 and 5.3. However, if you're creating PDF, you wont' have page fidelity between the PDFs produced by 5.2 and 5.3. Liz
