Advanced Post Slider: thumbnails do not appear

Hello,

I am using Advanced Post Slider for my blog http://theoff.info/wordpress/.

I have selected Thumbnails option in the template. But thumbnails do not appear in the slide show.

Secondly, title is too big for the slide. I have changed Title font size to 10 or 14. But there is no change in the size.

Could anyone help?

thanks
