Hi all, I have a quick question for you. I really do not know how to purchase the XPax product in the main HiFi website (https://hifisimtech.com/). When I went to the main HiFi website and searched products, I saw only 4 products. When I clicked on "Downloads," I saw the XPax update. When I tried to download that, it said that it requires XPax Service Pack 1. Am I going the right direction? Can anybody please help me? Regards, Baadal (Neel) Dhingra
