If I..

If I delete the Opening.avi from my Maple folder, would anything happen?

If that is the video that plays everytime you start maple then you don't need to delete it really. I always click the 2 white background images to proceed to login faster. I saw my roomate start maple and a video poped up, I was like "what is that?" and he said it always plays when you start maple. I just never saw it cause I clicked thos eimages first.

Deleting it will just bring you straight to the login screen, just like pre-Big Bang.
