I can't see my gallery screen anymore?

So for some reason I can't see anything on the gallery screen its just blank?
The program loads great & it seems like all the pictures loaded up fine to but I can't see them or the gallery? I've also deleted and then reinstalled the program but I'm still getting the same blank screen...

What should I do to fix this because I really need to get this gallery made for my website...

Thanks

Try this : go to Options, and click on the "Gallery Theme"

In my case it reveals the gallery.
