As I was still in 4.52 and saw 4.61, I upgraded to it.
Running Pmail in wine.
As always I took the upgrade function.
When starting Pmail it crashed after I had selected the user to open.
I decided to go back to 4.52, as this one was working and took the update function again.
When starting this 4.52 ad selecting the user, it crashes also now.
So I am without pmail for the moment.
What is the best way to recover?
