Auto-find Matrix doesn't work. It runs but it does find any matrix. But when I manually choose a matrix it works with the subtitle. I'm using Subrip 1.56.1 in Window 10 64 bits. When I use it in Windows 8.1 64 bits, it works properly. I'd appreciate any help. Thanks in advance.
Have you checked the path to your Matrixes?
I tried it on both systems you wrote and it works...
