are you able to use Nokia 7210 or Nokia 3510i Content Authoring SDK stand alone (without NMIT 3.1)? Do you remember which one you have installed first: the Toolkit or Content Authoring SDK? At least in Nokia 3510i Content Authoring SDK behaves so that if you have installed it before installing NMIT, the SDK installation procedure does not find the NMIT installation and so does not install the SDK in the NMIT subdirectory. In this case, you can run the SDK standalone, but not with a subsequently installed NMIT.
