I am having the same problem using a dreamlink system and IPTV66. It keeps asking me for a login and password and it won't accept it. Am using my donation number as the login and password. Have tried it at least 10 times and no go. Can someone please help me?
It was working fine and suddenly it is now asking for password and login. Very frustrating! Can an admin help?
