Kess v2 Clone on Ford Focus 1.6 TDCI MK3 EDC17C10 CAN ''checksum error'' solution

Car model and ECU type: Ford Focus 1.6 TDCI MK3 EDC17C10 CAN
Using a Chinese Kess v2 Clone

Error: ''checksum error'' every time when reading my ECU.
I updated my DLL files and today I managed to read the ECU without any error's.
But now when I try to check the file with WINOLS or ECU Titanium all I can see is that the file is empty.

This is my original ECU file

Working solution to empty file 
1. for sure its not empty.

2. Working solution to ''checksum error''
I replaced the DLL's from the attached file.

Suggestion:
Bought a second one kess v2 5.017 with a red PCB. It works fine.
