Entry_FindByDateInterval Error on return

Hi

First off all, i'm kinda new to all this API, so please feel free to ask me to elaborate the below if needed.

I've been trying to use  "Entry_GetDataArray" to get data from e-conomics to excel with VBA.

I'm combining is with the "Entry_FindByDateInterval"" to request the "Entry_GetDataArray".

But when i'm getting the response it seems wrong - I get this text string: ""soap:ClientEconomic.Api.Exceptions.ValidationException(E04040): Unable to parse message. (id=4c9ec556-0a14-4b11-8348-847cc017fbeb)""

So i was wondering if anyone knows why i'm getting this and how to fix it? :)

Kind regards
