Granulator II opened outside of M4L won't let Live in turn on

Hi,
As above, if i open the M4L file in an amxd~ object, everything works other than the Live In button - when it is clicked it just goes darker grey. I think this is because the button is not set as active, and having poked around the Livein subpatcher there are message boxes which look to activate it (and the grab button). I just changed the message boxes from having the $1 follow the message, to just 1, and this has activated the Live In button and i can now grab audio (from the Granulator Input buffers, this device works fine in an amxd~ it seems).
However, just cos i have made it work, THATS NOT GOOD ENOUGH. Because i dont have a clue why the variable message boxes aren't receiving thier own active (1's) from the rest of the patch, when the same device opened in M4L works fine without any editing. And that drives me crazy. If anyone could please explain whats going on, it'd be much appreciated. The edited (no $1's) Granulator device is attached.
