I am using the same version of the app without a problem on the same Nook Tablet when booted to CM7 from an SD card. The app also worked when I was rooted and on version 1.4.0. I took the NT back to stock this week when I made a bootable SD card.
I have tried uninstalling and reinstalling the app and resetting the NT. But, I get the same error.
I run from the SD card most of the time, so this hasn't taken me out of commission, but it bugs me that I can't get it to work. Has anyone else encountered this problem? Has anyone found a fix?
