Christmas 3D Tree

hi loving this live CHRISTMAS tree, but having some trouble with it, it keeps going off the screen please can you fix it other wise I will uninstall it as I pay for the full version, and this why I don't like PAYING for wall without having a trial run so hopefully you can fix it please as it very nice and it will be a shame to have to uninstall it as I will loose my refund as that don't last long enough well fingers crossed that you will sort this issue thanks x

This is a incredibly beautiful live wallpaper, it's my favorite Christmas Live wallpaper. I especially love that every aspect of the scene can be set on color cycling mode. However, it was working great, but now, when I set it as my Live wallpaper the screen is just black. Also,, when it did work, the Background stars were only on the top portion. The preview still works but the live wallpaper doesn't. I really hope that it gets fixed asap I really do love this lwp.
