2013 Project trial download, delete my ability to reply to outlook emails and uninstall didn't reverse this problem. URGENT!!

I downloaded the 32 bit trial version of 2013 Project to try it out. It messed up Outlook, won't allow me to reply to emails, and is giving me an error that I need to upgrade from Word 2010 to Word 2013; and, even after uninstalling Project 2013, the problem didn't go away. I CAN"T RESPOND TO EMAILS. THIS IS AN URGENT PROBLEM FOR ME. Help...
