That website seemes to be using the Mac version or an older version of Pro Tools. The "Windows" menu isn't ordered like that anymore :/
The other solution of using the "Manually find and relink" doesn't work for me either.
Dragging and dropping the tracks in the candidates window simply doesn't do anything. No error message or loading buffer, just nothing.
edit: got it, you had to select both the file you found and the one you're searching!
Thanks guys
