Have you tried re-starting your Kindle? Home > Menu > Settings > Menu > Restart. Sometimes a re-boot can clear up problems.
Edit: I see you tried a restart already. How about going back to factory settings. Copy your Kindle's documents folder to your computer first because it will wipe out everything and you'll have to re-register.
