Error in IE 9/10

Hi, I’m getting an error message in IE 9/10 that the type or url is invalid, which isn’t true as it works in all other browsers and devices. I’m using Cross Browser Testing to check IE as I’m on a Mac, so perhaps something is going on there, but this is the page I’m testing:

any thoughts as to what’s going on? also, I’m using the simple method of just pasting the url into the page/post.

thanks!
