OK, Hert suggested I share the import profiles and the script, so that hopefully someone here can try them out and see if they get the same results.
First the script:
The way this script is supposed to work (and always worked for me perfectly before upgrading) is this. You add it to the Download Profile it as pre-script. When you run the profile, a pop-up box asks you for a prefix (e.g., "ASU_", "DX_", whatever...). For each prefix the script then generates a four digit counter number (with leading zeros) and then stores the last number after renaming in the registry. That way, if you run the script again using the same prefix it remembers what the last number was and starts renaming at the next number.
The script also renames pairs of JPG+NEF files with the same counter number, i.e.:
_DSC0789.jpg ---> DX_0001.jpg
_DSC0789.jpg ---> DX_0001.nef
_DSC0790.jpg ---> DX_0002.jpg
_DSC0790.jpg ---> DX_0002.nef
_DSC0791.jpg ---> DX_0003.jpg
_DSC0791.jpg ---> DX_0003.nef
_DSC0792.jpg ---> DX_0004.jpg
_DSC0792.jpg ---> DX_0004.nef
etc.
Here that script:
[Needs to be placed into \Scripts\ImportScripts]
Now the download profile(s):
My profiles are very simple. They download the files into a subfolder with the date, which resides inside a folder named by the year, thus images shot today would end up inside:
G:/Photos/2018/2018-12-01/
Here the download profile that works with the script, but unfortunately is not reliable, because it skips some of the images and thus makes a mess out of the renaming (and does not remember the correct, new, highest counter number):
Then supposedly the one where the script is disabled, but oddly enough files are still renamed (and skipped!):
And, finally a new Import Profile, that downloads the images without skipping any, but does not rename, even though the script has been added:
Thanks everybody for testing and reporting the results. I really hope to figure out, why this no longer works...

[FYI - I had to ZIP these import profiles, else the forum would not let me upload them; unzip and place them into \\PSU Catalog\ImportProfiles\]
