Hi Stefan I'm on vacation right now, but will try to have a look in a couple of weeks. In the meantime... * which version of the cewe editor are you using? * does cewe2pdf work if you "save as" .mcf from the editor instead of the default. mcfx and process that? * any chance of creating a small mcfx which exhibits the problem and uploading it?

My parents did create the photobook and I just returned from a visit. I'll try to figure over VC if we can check the version and maybe also export to mcf. Maybe I can also get a test file - will keep you posted.
