For some weird reason it can't load this file (though it can load everything else).
I have tried with both the installed and portable versions.

Thanks, but WFM, I don't experience any problems loading this MKV file.
Apologies, I don't know what happened. Mine loads now as well.
It must have been a temp bug.
Consider the matter closed.
