Read about this earlier, Infomir were facing legal action over allowing there boxes to access illegal content, they now have a black list of IPTV companies which there boxes block, that list is growing.
3 courses of action
1) Use a android box with STUEmu
2) Ask your provider for a new portal
3) There fave been reports of rolling back the firmware solves the issue
I wouldnt think so either, so I have mailed them to ask if they are official. Im trying to pin point where the block is as some work and some dont. Just now its pointing to MAC blocking rather than provider blocking.
