When I open Rassler.exe I receive this error message.  Any thoughts on what would cause it?

Error: main.lua:290: attempt to call field 'getInfo' (a nil value)
stack traceback:
        main.lua:290: in function 'loadFileAsTable'
        main.lua:121: in function 'load'
        [string "boot.lua"]:440: in function <[string "boot.lua"]:436>
        [C]: in function 'xpcall'

im having the same problem on Win10 Home
