Hi! Have you been able to buy a license? It seems that they don't spare free license key nowadays and the purchase option in the official website doesn't work anymore.

Hi. Unfortunately, I have not been able to buy a license. I wrote to Dr. Friedrich's colleague and received the following answer: "Thanks for your inquiry. I had to conduct some research and found a colleague from our department who was (or is) also using this program. His name is Dr. Thomas Huhn (Coworker of Prof. Gaich), and he faced the same problems as you. Thomas told me that he was in contact with the son of Friedrich Menges. Unfortunately, no one has access to the license server of the program, so it is not clear how the problem can be solved in the future."

Thanks for your quickly reply. It's a pity.
