Thanks for the response. Sorry for not being clear. I meant that the DynDOLOD_Tamriel.txt files are not created, but files with similar names with string _Objects appended to the name, e.g. DynDOLOD_Tamriel_Objects.txt are created. One of these are created for each run of dyndolodx64.exe for each world that is checked: e.g. DynDOLOD_Tamriel_Objects.txt, DynDOLOD_MarkarthWorld_Objects.txt, etc. The corresponding files without _Objects appended (or non _Objects files, as I called them) are not created. The on screen error messages are something like Cannot read index data in DynDOLOD_Tamriel Cannot find master data in DynDOLOD_Tamriel Cannot find bunchofnumbers in DynDOLOD_Tamriel The MCM is showing as deactivated with the last message: being the master data one above. I've gone through the FAQ's and instructions but have probably missed something obvious. Additional Log file here. Not presuming that they are relevant, but if it is something to do with the dyndolodx64.exe generation then they might be. This file was too big and had to be zipped.
