Hi Ad
The WMS protocol is not static. At some point, in a new version, 1.1.0) it was decided to add the Service parameter to allow the same server to publish various OGC services.
I tried accessing the service in question with the Service parameter:
https://service.pdok.nl/rws/ahn/wms/v1_0?Service=WMS
That seemed to work until the table was to be opened with the selected layer. I got the same error that you referred to.
I opened the XML file that is created with the TAB file and noticed that the Service parameters hadn't been "copied" onto the GetMap URL. So I manually added the Service=WMS text onto the URL
I saved the XML file and reopened the WMS table using the existing TAB file and now it works.
I have attached the table (TAB and XML).

Many public data are available in the Netherlands as maps, through a viewer or as a web service; I have been using these for many years.
Recently however when trying to accees a WMS web service like https://service.pdok.nl/rws/ahn/wms/v1_0?request=GetCapabilities
I receive a message "the service issued the followig exception: MIssing key: SERVICE".
A local discussion points at Mapinfo as te culprit.
I would appreciate any help in trying to restore this service.
