I tested
@Ghost2140 (thank you!) file and I still have the same error that I attached.
As I told I have this error
1) after the procedure with VIN decoder: copy/paste the codes in the PR space, as I described in the previous post
2) before putting any txt fil in the FGST folder
3) with my txt file in the folder
4) with
@Ghost2140 txt in the folder
5) after deleting txt file from the FGST folder (returning to point 2)
So I think the problem is that PETKA is still reading
somewhere the file created with VIN decoder and continue ignorig the txt files
Support accepted!
EDIT I FINALLY SOLVED THE PROBLEM! Here the solution as It could be useful for others:
The problem is that PETKA is looking for the files in the path X:\ProgramData\Digital-Eliteboard\PETKA\USERDATA\FGST
BUT
The path of installation may not be that one, it depends on your Windows version and language (mine is italian) I think.
In my case it installed the software in the path with the italian translation of Program Data --->
Programmi and with (x86) maybe because my windows is 64-bit and the software not, idk.
So after I activated the option
View hidden files and folders in Windows I finally got the ProgramData folder visible in the C: drive.
So if you have this problem try this solution, and be suspicious if you have to create the folders USERDATA\FGST because they are not in your software path as it happened to me!
