I have about 75 books downloaded from B&N to my simple touch glowlight (and no sideloaded content). But when I try to download new items i get a message that says "We are having trouble downloading - your nook's memory may be full. Try archiving items in your library and try again". Archiving actually works, but everything I've read suggests one should be able to load "thousands" of books on these devices. Device info only tells me how much "sideload" space available (240 MB out of 240MB). It appears I should have at least 750 MB free for B&N material. Can that really be full with 75 books? (granted, some books take more space than others, but still...)
