Wild media server (UPnP, DLNA, HTTP)

Hi everyone,
Need some help regarding connections.
I have a Sony BDPS770 I had it connected wirelessly with a License. I decided to see how it would handle with a wired connection and recieved a 15 day license to try it out. I have since gone back to a wireless connection but now it will not work.
The device is showing but it now has a new device code for the wireless connection. Therefore the license that I paid for for that wireless connection is no longer valid. Even though it still has the same MAC address and everything?

Please Help
Thanks

Hi,

The Device Code based on MAC-address of device. Another the Device Code mean another device accesses the server. Probably WiFi bridge, probably another WiFi adapter. No variants.
