Anja,
Thomas Hensel is the owner of the project, but he can no longer access to the repository, so I think that he can receive his original code.
I'm trying to help the community to have the code back again. All the people that are requesting this code are still waiting to find a way to download it, I haven't shared it due to the OLD Code Exchange licence, even if I can access the repositories since the beginning.
What we are seeking is an help from you.
Best
Ivan
