Just updated and now I have lost EVERYTHING, emails, contacts, calender, everything - Help please

Forced to updated and I have lost everything. Folders, calender’s, contacts, thousands of emails. I had two accounts set up, Gmail and Hotmail. I know I can sync and download the emails again…I have thousands of emails. Is there any way to restore this program? 

Hello Lora,
sounds like you skipped the import from eM Client 6.
Please go to Menu>File>Import… and choose to Import from eM Client 6.
