[Q] Problem updating apps topic

I updated my Nook HD+ to CyanogenMod 11-20141122. It's working pretty but all the apps that I have downloaded from play store and aptoide will not update. I check for new versions and I can uninstall and reinstall to get the newest but all saved data is lost. I have included the specs below
