You misunderstand... I don't want to remove the message, I just want to automatically hit "Ok" when it pops up upon save. The message that pops up on saving is only a reminder that a different message will pop up if you open the file using a commercial version (which is fine with me).

It just doesn't make any sense that it would say:
"The file being saved was created by a Student Version of Maya intended for personal learning only. If you save the file, this message will always appear whenever the file is opened" EVERY time you want to save. Showing it on the first save would be just fine and achieve the same purpose.
