Trying to read a .txt file with delimiter from database extract

I am trying to read a .txt file with @^@ as the delimiter. The most success I get is from using the file reader (complex format) node but once it gets to a particular row it has an error. It seems to relate to a column that contains a lots of data that goes over quite a lines within the text file. It appears between the delimeters but the amount of data seems to confuse the reader. Is there another setting that I need to apply?
