Somehow amidst all my hacking and restoring, I lost access to the PDReader and PDLauncher apps. They no longer appear in the menu, and attempting to launch from the Homeswitcher or the Browser menu tray produces the "Application has stopped" popup. The apks are still in /system/apps; I've manually deleted and reinstalled them to no avail. This situation has persisted through several resets and restores, of both stock and hacked firmwares (currently on hacked 8/20). I really don't care about the launcher, but I'd like to have Reader back, particularly since the Nook app doesn't work. Any suggestions?
