Maybe You don't have errors but I don't know how can You use one 2014.Q3 .hnr with 2014.Q4 maps ???
Look at first picture in Your post - marked .hnr file is 2014.Q3 
Or should we use all old 2014.Q3 .hnr files with new maps like it doesn't matter?
My humble opinion is that they are NOT compatible, or am I wrong?
Just to clear things up, problem is not in LICENSES but in fact that maps 2014.Q4 ARE NOT compatible with 2014.Q3 .hnr files, and when You remove maps - You have NO errors.
And last thing, YES You CAN calculate routes WITHOUT or with INCOMPATIBLE (INVALID) .hnr files, because they contain only pre-calculated routes.
