Em client crashes after the latest version installation (7.2.33939.0)

I’m using the free version and I’ve just migrated to the newest version. I have to accounts. After the migration if I try to create a new email and I want to switch from an account to another one, Em client it’s extremely slow and then it crashes and restarts.

Can you post us the details from the crash dialog to support@emclient.com please? We will look into it, but it likely related to particular setup with signatures or security certificates.
