Problem With Next/Previous Arrows Showing in WPPA

I have edited the settings in my WPPA+ album to show the front and back arrows in the film strip… it all worked fine yesterday, and now I went back to it today, and they don’t show. if you hover over the area where they should be, you can see the mouse change to a hand, but when you click nothing happens. I also set the album so if you hover over a film strip thumbnail, it would show in the main photo area… I’m a little new to Word Press, but I seemed to have done it right yesterday and now today it’s messed up. I’m announcing the new site Friday and hope to resolve it by then! Please help!
