Welcome to MobileRead and the PE, isalivia!
I'm glad you found a way to update your PE. Thanks for sharing your experience -- someone else may be going down the same path you did.
I hope you had no trouble hooking up to your library. If you did, give a holler. That's one of the few things I actually know about! (Although I usually put my library books through Calibre before copying them to my eDGes). Having access to library books is one of the great things about the PE and EE, in my opinion.
