Can I use Dev Dashboard / my license on a localhost?

Hi,

I own a WPMUDEV license. I downloaded and installed Smush Pro (as a zip file) on my localhost. Big picutre, I'm trying to test pro Smush on a locally hosted site (ie. not accessible from the outside).

But, it tells me I don't have Pro features available. Login to Dev Dashboard just spins...

Is there a way to enter my license and test Smush Pro locally?

Thanks,
Greg
