Columbia App issue

I finally got down to taking a look at all questions of all the schools i am interested in - HBS, Wharton, Kellogg, Ross, Chicago, Tuck, Insead etc. I have also jotted down some ideas as to what I would like to say. I am having difficulties in Wharton's failure essay and also some culture shock essays. But I will delve deep for instances of those later. BTW, I am trying to access Columbia's online app but am not able to. The page never loads. I have tried using both Firefox and IE. Is anyone else facing a similar issue?
