I am unable to save the component LTNG_Access_Control_Challenge_Wrapper.cmp at all. This is also true of the wrapper file in the demo. Any time I make any change and attempt to save either file, I receive this error:

Failed to save LTNG_Access_Control_Challenge_Wrapper.cmp: An unexpected error occurred. Please include this ErrorId if you contact support: 510282782-23865 (167693694)

Thanks for any help / suggestions
