Hi, Not being familiar at all with such a receiver, but indications are that you have not aligned the dish to Hotbird properly if at all.
If it is possible to monitor the signal quality on a polsat transponder you should be able to align the dish using that.
Set the dish elevation according to dishpointer.com using 13E and your location, and point the dish in the direction indicated by the yellow line. You can use this as a starting point and then sweep the dish around this position whilst monitoring the transponder until you get a signal.
