I can't reminder the full details cos I'm sleepy, but based on new scriptures found, multiple languages were used in writing the earliest form of the Quran. So the meaning of some if the passages is in question. I suggest you watch it to avoid being lost in translation.
No because as it was said the Qur'an has been passed down for centuries by the oral tradition. To this day there are many many people that know the Qur'an by heart. Everything can be cross checked for potential errors.
Besides these guys are trying to read it in Akkadian language when the Qur'an as everyone knows was revealed in Arabic.
