Errors occured while navigating work with talend Data Preparation Free Desktop 2.5.1

Hi guys,

 

i don't know what i do wrong.

FYI: In front of this installation, i installed already the further version and deinstallaing all.

 

The Problem is, that i even get the failure

An error has occurred

Sorry an unexpected error occurred and we could not complete your last operation, but you can keep using Data Preparation.

 

If i delete a a row or coloumn or swapping columns ... The point is, after the error all changes be done,. 

That happens on new excel files and the sample dataset.

 

What can i do, that it works?

 

Attached the overview of the dataset. Why there all grey and not green, withe or orange?

The second file are the errors after one change
