unable to import csv-Data

Hello to all,

I am trying to import some data from a csv-file. But I am absolutely
unable to get any usefull result.
I have tried several options to do formating during input, but in every
case Mathematica 8 puts several csv-columns
into one result-column.
Because the csv-data contains germany encoding, I have tried several
conversion options, but nothing helps.
Here is a snapshot of the csv-data (one headline two datalines):

I have tried the following import-command (and several versions of it),
but did not get useful import-result:
imp = Import["test.csv", "Table", "FieldSeparators" ->  ";",
    "DateStringFormat" ->  { "Year", "-", "Month", "-", "Day"},
    "CharacterEncoding" ->  "ASCII", "HeaderLines" ->  1] ;

For me it looks like the CSV-Importer is unable to detect NULL-Values (;;)?!?

By the way reading the data into excel, writing a resulting xls-file and
importing the xls-file into mathematica works out of the box,
but I can't go this way because there are more than 200000 datalines,
and Excel did not support such a great amount and Mathematica
was unable to import Excel-2010-Formated xlsx-Data (ods didn't works
also because of the great amount of data).

Any help would be highly appreciated
Kind regards
Andre
