IE displays spry submenus (incorrectly) at top of screen

Question

I apologize for asking this question, as it looks like it has been asked before, but I've spent hours trying to get my spry navigation bar to display correctly in Internet Explorer with no luck.  My project for school is due tomorrow and this is the ONLY thing that is preventing me from completing my project.  I'm practically in tears!
I use a horizontal spry menu and the submenus don't drop down like they are supposed to.  They show up as separate navigation menus at the very top of the screen.
What additional information do I need to provide?  My mentor was unable to help me because he uses a Mac and he can't test it.

Hi Katie,
I understand. Here is a revised style sheet. I cannot verify it because I do not have version 1.4 on my computer. Please try it, make sure you keep a copy of your own style sheet in case. After installation please give me your feedback.
