I need a little help here. I had a lightning strike that took out my LNB. I had a Dish 500 system (legacy). I replaced the LNB with a used Dish 500 Legacy. One problem, now that I have switched LNB's my system only has the capabilities of the previous Dish 300 subscription package and I've lost the additional benefits of the Dish 500 system. What do I need to do to get the extra programming I am paying for. Many thanks.
