What you can do is this:
Open Safari, click on Safari in the menu, go to preferences. In preferences, click on the advanced tab and at the bottom tick the box that says 'Show develop menu in the menu bar'.
You may have to close Safari, but now when you open it there will be a 'Develop' menu in the menu bar. If you click on this menu you will see 'User Agent' this is where you can tell Safari to emulate other browsers including IE and that should resolve your issue.
