Syntax Error – Plugin Won't Load

Using WordPress 3.5.1 with WooCommerce 2.0.5. I installed the plugin and that went ok, but when I went to use it, I get a quick dropdown message that says “Syntax Error: Syntax Error” and then the page is blank except for the brief title at the top and the facebook “like” information. Please advise. Thanks!!
