Right margin wonky and menu bar going to two lines

HI, The right side of my site is no longer aligned and the menu bar is going to two lines! I didn’t do anything to the code. We are posting a new blog article tomorrow and would really like this fixed by 6am on August 10, Los Angeles time. Is there some code I can add to the CSS on Theme Options? Please help! Thank you!
