Bad or missing serial number on IPTVSTALKER kodi

[bigshadow]

Hi can anyone help me with this issue. I was able to see TV on IPTVSTALKER Kodi. Now when i try and go in, it says Bad or missing serial number. Not sure whats going on I haven't moved anything. I still have 100days on my rocket so i dont see how that can be a problem. Can someone please give me some feedback on whats going on or at least have a clue in fixing this problem. Thanks in advance!
