When using Pluraleyes

Hi team

Does anybody have any idea why the syncronize button isn't highlighted

I've loaded my footage onto the templete button the sychronize button is unhightlighted so I can't access it.
I shot with two different cameras, Seinhiesser mics on on one (and

receiver mic on subject), recording sound through the camera on the other.

I've attached a screen shot

I hope your well and busy

Thanks
Neil

here is the screenshot

just curious. why are you using Pluraleyes when you have FCP X that does the same thing?

how does FCPX do it, I must have missed that ?
