Hi Scoots, welcome!
If your eDGe does not update when you check for updates (using the "Update" app) you can follow the instructions posted here:
https://www.mobileread.com/forums/sho...d.php?t=134237 (especially post #10) and here:

As bouldergramp (another new owner!

) pointed out in another thread, when you get a screen with a green lock symbol on the lower left, drag that lock all the way to the right and you will be opening Ermine on your PE.
Good luck!
