 + 
 +:!: **NOTE**: The identity of PIXILAB Player is now based on the primary network interface's MAC address rather than the active interface's MAC address. The advantage of this method is that the identity of the player will remain the same even if you switch network interface (e.g., using both wired and wifi). However, if you previously used another network interface than the primary one, the player's identity may change when you update to Blocks 6.2, and you will then need to re-assign it. Players using a wired connection (with a single Ethernet jack) shouldn't see any need to re-assign their identity. Nor players that aren't based on our PIXILAB Player software, or where other means are used to identify the player.
