Version 2.3.5.0 I've added a small feature to help decrypt element files... It appears that the only things encrypted in the elements.data are the version and the number of items in the first 40 lists...
So I created a way to manually set the version and the total number of items in each list using a text file... I included an example file "elements.list.count" that will work with Epic's latest element.data... Place it in the same directory as the elements.data file when you load it...
I also added some detail to the error loading dialog to help in determining the list counts as they change in the future... Create or edit elements.list.count file via text editor... Once you have a elements.data file loaded, you can create an elements.list.count file in the tools menu...
