Ok guys, this is exactly what I have done, and apparently it is working now.
1) System>Add-ons>My Add-ons>PVR Clients>Stalker Client>Configure>Portal 1>Serial Number (right here I put a any random number with 13 digits)>Device ID (I put a random single number)>Device ID2>(I put a random single number)>Signature (I put a random single number).
2) Then I went to https://papiao.is/main/search_nfps and because I was not able to update my same MAC address, so I changed a single digit (for example 79 to 78) and saved, and then came back and put again my real MAC address (with 79) (the one I donated) and saved again.
Try this after you have fix serial, go into setting, tv, geneal. and click where say clear data cache, click, yes when ask you yes o no, after that you will good to connect..
