Layout seems frozen after WP update

Hello-

I updated WP to 3.5, and my Blocked Theme (downloaded from ThemeForest) seems to have some hitches. The homepage photo slider stopped working, and became static. Also, I can’t edit as easily in the layout blocks, which seem frozen.

There doesn’t appear to be an update for the Blocked Theme. Any other ideas on getting the homepage slider and gallery working again?

Thanks.
