I'm running Windows 10 Pro and I am also having a problem when attempting to rip a Blu-ray with the newer versions.
First, it's very slow to open the disc, much slower than the earlier versions that work. As noted above, when you do get to the rip process, it starts, but that's it.
After installing any of the newer versions I find myself having to go back to version 9.2.1.4 (I don't have version 9.2.1.5 but it is noted above to also work). The discs open much faster and the Blu-ray ripping feature works with this version.
