I have a stock rooted 1.1.0 and am having problems installing non-market apps. I just flashed back to stock and re-rooted with autonooter 3.0. I was having this problem before, not being able to install apps from ASTRO or through Titanium Backup, and was hoping flashing stock and re-rooting would fix this issue. The box is checked in the nook tools settings for allowing non-market apps but it doesn't let me install. All help will be greatly appreciated.
