NFPS / Private Device Conflict - Mac Address Mismatch

[SONY007]

Im just trying to setup a second IPTV on another Kodi after I upgraded it from isengard to 16.1. I'm using stalker client and I've set 2 up already in the last few days, all different mac addresses, but on this final one I want to set up once all the info as been added into the configurations and I enable TV I keep getting the message Device Conflict - Mac Address Mismatch'. I've checked and double checked and I can't see what the error could be. Any ideas anyone?

Thanks

Okay i've got it working now, basically what I had to do was enter 6 digits in device ID - device ID2 & Signature, previously device ID & ID2 had 2 digits and the signature had 4 digits. Even the previous 2 IPTV I setup the other day only had 2 digits & 4 for the signature and they work fine so I don't know.
