There's 50 things that could stop U from receiving channels...U need to READ and LEARN about your receiver, hardware, dish alignment, keys, software, etc..thats why there are MANY reputable Dss satellite forums with manuals, files, guides etc to read from and learn...they are listed in the "Recommended reputable satellite sites" thread here..the FLU (Fortec lifetine Ultra) is a very simple box to use..
and when U post and ask a question, its best to describe IN DETAIL, the problem and your setup with hardware, and what U have done to correct it....good luck
