This error means that an internal data structure had not been assigned to a "deck"object. This could be triggered by a problem in the DAE application (like a third party sequencer), a problem in DAE itself, or unsupported hardware.Verify that all needed software and drivers are present in the DAE Folder, and that the versions of DAE and the DAE application are compatible with the installed hardware. (For example, launching Logic Audio with DAE 1.09 on Sound Tools II hardware will post a -9025 error. Installing DAE 1.3 resolves this.)
