To the best of my understanding the "internal error" itself means in that strange error message coded way of speaking that the NX software blames the operating system for its problems. So whenever you do get such an error message the things to do are to attempt a part cleanup, reboot your system or try another machine if you have one available to attempt the same remedy on you part. Usually one of the above is sufficient to solve such errors.
