We are having two issues with your Woopress theme only with Internet Explorer (works fine in other browsers like Chrome)
1. Our product images are not showing up on product pages or getting cut off halfway. (We made the product images the same size as your demo.) This only happens in Internet Explorer.
Example: http://www.spectrumfacility.net/product/hot-water-pressure-washer-1-75-gpm/
2. On the checkout page the State selection dialog box is malfunctioning. It will not let you choose a state or continue with checkout. This only happens in Internet Explorer.

We have tried this on different versions of Internet Explorer (includingmost recent) and on different machines
