Don't sweat it, replacing the screen protector is really easy. You might have a harder time getting the old screen protector off unless a corner is already lifted.
Make sure to follow the directions in the DGX Product Attachments page. It's for the older Predator model but the principles are the same. I used straight 70% isopropyl alcohol without diluting. You'll also want to keep your fingers wet, and optionally use a credit card or rigid plastic edge to smooth out bubbles. If there are still any bubbles remaining or if it's not aligned correctly the wet application allows you to remove the screen protector and re-try. Alternatively any bubbles will be pushed out by water pressure the next time you dive.
