No Signal Why?

I have been watching White springs for a year now and all the sudden I
cannot pick White springs. I have a brand new KU lnb and I can receive other
KU signals OK.
I called the Tech. at white springs and asked if they are having any
problems with sending there signals that I cannot pick up White Springs?
they told me that there signals is AUK that they are sending there signals.I
do not have trees blocking my line of site.I can pick up the sat next to T-7
OK.
Here is the Inf.. that I put in and no luck.
Thanks for your help.
