Looks super great but doesn't work in Internet Explorer

I input a facebook api. I do not have a twitter api.

I asked it to put the icons on the login page.

Go to wp-login

It keeps coming up with a javascript error that asks me to close the page. Over and over. It will keep displaying the dialog until I finally give in and close the page.

Any ideas?
