Didn't Graduate

So today I got a letter in the mail saying I was removed from the Spring 2009 graduation list at Missouri State because "Lacking 1 of the 125 credit hours required to graduate" I was confused, I had 128 hours of credit. I spent 45 minutes on the phone with a very nice lady in the graduation department who explained I only had 39 of 40 hours in upper division... Apparently my advisor forgot to forward an e-mail to me in FEBRUARY that I was lacking 1 hour. The worst part of this is that I've had 3 advisors this semester, 1 quit, 1 was a temporary and than the last and final one is a newbie! So they aren't sure which advisor failed to e-mail me. In addition to this are 2 mistakes from a previous advisor that added to this one. My sophomore spring semester I only took 14 hours, my advisor advised me to not take more than that because "my classes would be difficult" this left me as a "sophomore" over the summer which meant that my financial aid would not increase yet. This meant that my financial aid WOULD have paid for my to go to Italy for 3 weeks in the summer but my advisor had advised me not to take that extra class which meant, NO ITALY. That class would have counted towards my 40 hours...
Than my advisor suggested I only take 4 hours of Internship classes last summer instead of 6. I did all the work for the 6 hours but didn't want to pay the extra fees to take the extra 2 hours so I agreed. This also would have counted towards my 40 hours... My advisor technically screwed me out of 5 hours that would have counted towards my 40 hours and instead left me 1 under and NO ONE CAUGHT IT!! Not until June 1... 15 days after my "Graduation" this means that starting Monday I will be taking a summer school class so I can GRADUATE in August!
My teacher is one I just had last last semester for Business Law and he actually made it interesting so I'm not completely dreading the class. Luckily my work is very flexible and will let me out of work from 1-2:50pm on Mondays & Wednesdays to take my class. It just means it will cost me $270 plus book materials to get my diploma which I was pretty sure May 15th I was going to get!

My mom said that I WOULD NOT be getting another graduation party... :(
