BP Corporate: ie8 not loading styles

I have been using BP corporate 1.3… for a long time. I made the mistake of upgrading WP to 3.3.1 and then the theme was not working correctly, so I upgraded the theme to 1.4.4. Since doing that the theme will not display correctly in ie8. No colors, Menu dropdowns are off, form fields out of whack, etc… It is as though ie is not seeing the style sheets? Firefox and Chrome work fine.

This is a private site so I can’t direct you to the site.

Any thoughts?
