wow, thanks Nick. I'd say you stumbled upon some sort of "bug" because that could be disastrous, as you have probably already figured out! So the ini file in the project folder was named "Revit.ini"? I encourage you to file a SR about this. We can quickly solve any issues that could arise from this by adding a line to the script to delete any "Revit.ini" files (if that's the correct name) that are in the project folder, to be on the safe side.
