Help Please – Mother's Day Photo Frames and Wallpapers Review

This is not bad BUT I have paid the full price and although now have access to all the photo cutouts still have no access to the wallpapers or clip art - it keeps telling me I have to "upgrade (null)". Have tried refreshes/ installs etc but nothing. This makes this a very expensive app for very little functionality. Please resolve.
