If you flashed the latest image, it would have the latest xml file. But no harm done.
You either have an alignment or hardware issue. You are going to have to investigate which it is. Please list the frequencies you cannot receive signal on. Use signal finder to check the ones I listed above. ( I have edited the list owing to an error and some missing entries)
Performing single satellite scan (as in post 4) is a good indicator of how many channels you get. Plugins like AutoBouquetMaker (ABM) and Autobouquets 28.2 (AB 28.2) read the SI table and import channels even though you cannot receive them. Post back with the result of how many channel you get.
