Alright, I have a big presentation I need to practice for tomorrow, but my powerpoint keeps freezing whenever I load the file. Other files seem to work, but not this one! It opens the file, displays the main slide but stop there. I can neither open or close PP after this and resolve to ctrl + alt+ del to close it. I've left it load for over 10 mins, but nothing. HELP!!!!

POST ANY SUGGESTIONS!!!.. I REALLY NEED HELP!!
