I managed to decrypt most of the Scenario Planner files. Coming soon in in the TSW2 upgrade for TSWTools (which will be named ToolkitForTSW). It is still work in progress. I still need to solve some technical issues and add the services layer to this screen. The first version, will only allow you to see the contents and export it as a zip file, so you can share scenarios. In the next version I likely will support cloning a scenario and then move on with other hacks.
