How to Fix VXDIAG BMW WinKFP ECU Blank Problem?

Problem:
I recently got the 4.28 STA-D ISTA-P HDD for the vxdiag vcx se BMW scanner.
Today tried to use WinKFP 5.3.1, Launched and pushed “Choose ZUSB”, but all fields were blanked. No ECU family options.

Solution:

Files have to be imported through winkfp.

Install BMW Standard Tool and find out SP-Daten files. Use BMW Coding tool to update NCSExpert, WinKfp, INPA. Press button “update WinKFP” after you “update SP-Daten”. For WinKFP in particular you need to press the “Update WinKFP” button also, the same procedure is starting, but it put the files in NFS Folder, too.

So it has all of the correct files and assembly line data.
