can't see picoreplayer on my LAN...

Hi,

i'd like to install picoreplayer and LMS on a raspberry PI3. I downloaded last version, flashed the card, installed it in RPI, plugged the ethernet cable, plugged the RPI.
But i just can't find pCP on the LAN. I really feel like an idiot... I used IPscan, NOTHING!

I really don't know what's happening, searched on the net but found no report of such an issue.

If anybody could help, i could look at me in the mirror again :-)
