As there are still visitors to this blog complaining about difficulties to download from ADrive and Dropbox, once for all: the links will not die as long as I pay and - as I mentioned already last week - I will pay as long as I'm living. I just checked some of the links again and they all work perfectly.
I don't know the exact reason why some have difficulties, but my guess is that it is an Adrive and Dropbox problem occasionally occurring in some countries. The reason might be that too many individuals try to download at the same time. I said already last week that the only solution to these problems is to have a little patience and to try to download a couple of days or a week later again. Then normally it works.
In the future I will ignore any comments related to this subject, as it takes too much time to deal with them, time which I could use to prepare new posts. I still have many hundreds of recordings I would like to post.
Thank you for your understanding.
