Unable to open email folders

Unable to open email folders

I've been unable to open my folders for email for 3 days now.  All I get when trying to open a folder is a "Loading" message and nothing ever opens.  The only folders I can access anything in, are empty folders.  There is also a yellow triangle in the bottom lefthand corner of the page that gives this error message:
