ArcGIS Explorer Application Configuration Manager Crashing

I have developed a custom add in for ArcGIS Explorer, which all works well. I have four buttons in the Add In, which I am now trying to a custom configuration (so that they appear on the Home ribbon, instead of the Add Ins tab. Two of the buttons work fine - they can be added from the manager, I can save it, and then appear fine in Explorer.
With the other two, as soon as I try to add the button in the Manager, an Unhandled exception message pops up, and the Manager crashes (error message below).

The buttons that work are named butLayerManager and butRailLocator. The two that don't are butSettings and butAbout.

Very strange, and very annoying!

Any ideas would be greatly appreciated.

Well I have managed to solve my problem... The issue was that in my XML configuration file, I had 5 tools: butLayerManager, butRailLocator, winRailLocator, butSettings and butAbout.

The butRailLocator and winRailLocator tools essentially do the same things; the win version is a dockable window, the but is a windows form. For this project, we did not require the dockable window version, so i commented it out in the xml config. i.e.:

<!--<dockWindow
     id="winRailLocator"
     assembly="RailExplorer_ForExplorer.dll"
     className="RailExplorer_ForExplorer.winRailLocator"
     caption="Rail Locator (dockable)"
     largeImage="Images\winRailLocator_LargeImage.png"
     smallImage="Images\winRailLocator_SmallImage.png" />-->

Turns out that the commenting screws with the addin. If i remove the comments, rebuild the addin, all is fine and works well in Explorer and the Application Manager.

Incidentally, if i now go to add a new Add-in component using visual studio, i get an error saying "Invalid ArcGIS Add-in Project. Unable to add new Add-in item to this project." I haven't found a way to get around this yet though.
