I've been working the last week on setting up my store. I use firefox for my browser and everything has been working just fine. However, I discovered that it does not work in internet explorer - it looks like the css doesn't load nor do any images.

I've looked at some other zen-cart site in explorer and they work in both browsers - so I think it must be something specific to my cart. Anyone who could give some advice to me would be most appreciated as I have limited experience with websites.

The site is at http://www.mellowbutterfly.com/shop/

Thanks!
