widget seems broken

Hi,

Try as I might I cannot get the icheckmovies widget to work on my blog https://www.greeneyedguitargirl.com.I wanted to put the widget in my sidebar and followed the instructions. Doesn’t matter where I put it in the sidebar–it doesn’t show up. It DID show up as a h3 link to my icheckmovies in my sidebar (with no graphics pulled from checked list) for a few minutes, but now it’s gone back to showing nothing.

Is this a matter of the widget/plugin being incompatible with the most recent version of wordpress, or is there some other issue? I’d be very disappointed not to be able to use this widget as I was very excited to find it.

cheers,
Julia
