ok I have already successfully set up a mag 250, but I am having problems with the mag 254. when I power up the box I get infomir screen and it say "loading". Then all I get is a black screen and that's it? I have looked online to trouble shoot the issues and I have read that the software could be corrupted and I need to re install. I can not find a working link to the software. can someone please help me out or any other ideas to fix my issue. Thanks!
