I need my personal account back - where are my SmartSheets?

I received an offer for 100 SmartSheets in my personal account if I changed my primary eMail to my corporate eMail. I did so. I just logged in and now I'm part of my Organization's group and my sheets are gone. Please, how do I get them back? I've been on 2 weeks PTO and have 4 years of project work in my SmartSheets - I really, REALLY need them back! Help!
