+1 happened to me and this was the fix i used as well. case in point: anytime there are issues with an app, i clear cache and test. if it still malfunctions, clear data and test. one or both fixes the issue 9.9 times out of 10. only in rare instances have i needed to uninstall/reinstall an app (usually nandorid/TB/MBR restores with apps on sdcard).
reboot the phone after wards and all should be good.
