Textfile Input Error

hi dear kettlers

I am trying to put my Text-File with datas, which are separated with "|" and no tab, and in which the new rows of datas begin on new lines. see example below:

...
71298767|2012|633870|80.54|
71298767|2012|633937|132.63|
71298767|2012|634038|140.48|
...

In the Step "Text file Input" in Content>Format, i chose DOS. I am usin Windows OS. But why is the error: DOS format was specified but only a single line feed character was found, not 2


Appreciate your suggestion/help
thank you in advance
