μtorrent claims that tracker doesn't support download

I have already downloaded LibreOffice via the torrent, but when I look at the trackers list (I am now seeding) the

http://tracker.documentfoundation.org:6969/announce

tracker reports the following:

Failure: requested download is not authorized for use with this tracker.

I am using μTorrent 3.2 on Windows XP 32-bit

If this is about the 3.6.0 windows version, then it is because at first there were packages that were not code-signed. They were replaced by digitally signed installer packages. (the content itself is the same, only a signature was added)

The hash of the 3.6.0 Windows installer package should be:
e10a07352f9eb12a560b2bab3f37ebcfccc2466c

In all other cases your question lacks necessary details…
