After LibreOffice updated it won't start!

http://askubuntu.com – I read Seth's post here: How do I install LibreOffice 4?. I wanted to upgrade, so I ran the commands as provided by Mik to upgrade using stable ppa. For some reason now when I try to run LibreOffice it starts up, shows the splash screen, loads about maybe 2-3% and then quits, giving me an Ubuntu error. I might have only partially updated/upgraded, so this might be part of the problem...I'm not sure. HELP!! I really need to use LibreOffice for a Biology class I have. I can use Abiword for now, but I really prefer LibreOffice. I want to try and fix it, but if I don't get a quick answer I am afr (HowTos)
