Subsequent to the latest PDFCreator Server version we just released 2.0.1 which fixes the settings migration from older versions.
PDFCreator Server 2.0 brings a completely redesigned user interface. The main focus was to make it much easier to find functionality and to make configuring the application as easy as possible. A few larger features were added, i.e. the live monitoring and the C# script action, but we also made a lot of other improvements.
