Outlook crashed on Mac - cannot reach mail history

Today I started Outlook on my Mac. It seemed to be a new version. I went to "send emails" but that box was empty. Then it said it found my history of send emails and asked if i wanted to load them. I said yes so it started loading.

I soon found the send mail I was looking for and used it to send 2 files to the same adress I used earlier.

Soon after that moment Outlook crashed and I cannot open it again. The failure-report shows a pretty large list that I don't understand. What should I do?
