I am using this free template so finding it hard to figure out how to fix it. I think if this page gets fixed then the movie club page will get fixed too. The titles in the movie club page are off too.
I am not sure if my answer is too late for you.
I saw your code, and there are so much table tags with unnecessary td tags. Those might come from the free templates or you might want to add some other data.
To make it left align, set table width to 100% for all the table nested in Div #ContentPlaceHolder1_TreeView1.
The HTML would be cleaner if you change tables to unordered list (ul li).
