This week I was about to purchase it as my wife said i could have it as a Christmas present, but this week it has started to mess up.
I have quite a few more DVD's and TV shows on Blu-ray to go through and it has now started to come up with a fatal error and close,
even when it has opened the disc and is ready for me to select the streams to copy.

I have even gone so far as to format my computer so that MakeMKV is the ONLY installed program on my PC.
Still no joy.
Does anyone know what is causing it? A Windows update? Anything?
Any help here would be great as thankfully for now I have copied all my 3D Blurays as DVDFab doesn't do mvc mkv's and that is what I now have to use.
Thanks in advance!
