mail in Kontact 4.13.2 disappeared

[reggler]

Hi,

I just updated my Kubuntu install, rebooted and started Kontact which is my default email application - but now, no more email component is present. All the other components like Calendaar, To-do lisst, feeds journal and popup notes look like they used to but i'm missing my mail component, where hasit gone?
Is it time to select a new email client?

Thanks,
Ron
