Unable to recognize new elements

For some reason, when I add a new element, MCreator doesn't recompile. It gets stuck on recompiling the data and then the next time I launch the app, it keeps on saying there are errors and doesn't specify what is erronated whatever I do. I even tried ''Factory Reseting'' the app and getting multiple installers and making many mcr. files, editing my preferences... Just you name it and see that I did it.
