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: https://www.entourageedge.com/suppor...barticleid=265
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.
