With iptvRocket, you (the user) cannot change the donation/password login number (or maybe I am thinking of the server URL, I will need to re-check on that)
With nfps or iptv66 you can, but not rocket.
We need to know if you have the correct login thou, that should be first.
Click my name and send me a Private Message with the login info and your email. Then I can track it down for us.
And then if that pans out...
Thru that link I posted earlier, you do not have to read or understand that complete thread, just go to post #33 on that thread and download the correct N0_Block file for your Mag250 and install on your Mag 250,.
Install it thru USB and in the Mag's inner menus... if memory serves me, the 'Home Media' icon should open the USB, in order to install the file.
