Thank you very much for your 2ct 
64bit version is not possible, because I do not have a library for showing the models that can use 64bit.
I think I have detected just such an array as the cause of this and running at present a test.
So I might be on the right way. Thank you.

Edit:
It is now 20:18 in germany and datsville is still running without error messages. I think it is now half done.
It is finished now without any error.
The trick is to disable the preview image. Then it runs on my system without any error also with datville.
