Until today my Sat worked perfectly. I had not installed a new AR fix in a while (Feb I beleive). Today I tried to install a AR fix(DBPSW-070407P) from April 7 and it causes my menus to go fuzzy ( still readable) and I cannot scan any Sats (no signal on Echo 7 or 8 ) I reinstall the old fix and have signal again ( clear clean menus) but only scan back in half the channels I had before and after a few minutes I am searching for signal again. Any help anyone could give would be greatly appreciated. I am a little bit of a novice and the usual old stuff isn't working for me this time. Thanks! Also, I have tried to manually punch the keys to no avail.
