Hmm, that sounds indeed strange. Can you contact support@opgroup.de and send them that script? They'll look into it.

Ozgur: I believe the first field is 0, not 1. Indices start with 0. The other column numbers are probably also wrong. Can you check if it works when you fix the numbers? Datasets expect a date in field 0, so I don't know what happens when it is missing, but possibly the old version got then some phantom field and thus worked with the wrong numbers.
