I still have no success with this. I've tried all the settings perfectly and nothing. I edit the settings.xml and still nothing. I've been using donation number as serial which is only 12 digits so I just add a "0" at the front of it to make it 13 digits. I've used random 4 digit numbers for device ID1,Device ID2 and Signature. I have the same exact settings in my IPTV Stalker App and I can watch TV fine only from IPTV Stalker app. I cant get this to work with Stalker Client. I've changed MAC and relinked MAC to n success. Can someone please tell me something I'm possibly overlooking? I cant be the only one that is still stuck. By the way I have Stalker Client 0.8.4 and Stalker App 9.0.21.
After you disable your IPTV Stalker addon, go to the donation page and change your MAC address. IPTV Stalker uses its own set of numbers and the IPTV server will tie these to your account - hence having to reset your MAC address. I was doing the same thing as you also wondering why one worked but not the other.
