In the loadITGLibrary function, change the following:

 sub loadITGLibrary()
    m.componentLibrary = CreateObject("roSGNode", "ComponentLibrary")
    'OLD
    m.componentLibrary.uri = 
    "<https://assets.inthegame.io/roku/ITGLibrary_V2-6.pkg>"
    
    'NEW
    m.componentLibrary.uri = 
    "<https://assets.inthegame.io/roku/ITGLibrary_v2-7.pkg>"
    m.componentLibrary.observeField("loadStatus", "onLoadStatusLibraryChanged")
 end sub
