NullReferenceException after performing oil service reset

Everytime, after performing an oil service reset, everything works fine until the message "turn off the ignition for 60 seconds" appears. After a few seconds, the connection is terminated and the window crashes, returning to the main window in MES. The following error message pops up (apologies, it's in Dutch):

I believe the oil service reset itself does get exectued succesfully..

Any ideas what might cause this error?

I'd check for .NET updates.

Can you post the FULL exception information.

You should be able to enlarge the window and select and copy the contents.

Well, we've done multiple resets now, same results over and over again.
As the car has done several miles by now, I don't want to reset it again.
So the picture(s) above is the only one for now...couldn't enlarge the window, I'm afraid...

I am thinking a software bug. Try to update to the latest version 5.3 instead of 4.6.
