RAI is long standing issue with Diablo requires card to work or keys.bin with RAI Sept (soon Oct) key included & fausto Emulator to work.
InXWorld: 13E Free-XTV, Free-XTV2, Free-X Delight, XDreamTV & 10E Free-X Delight working fine here with original UW135 key.bin & my key.bin (and presumably other key.bin's)
CAIDs file requires CAID 0626 to be included or AUTO PMT [ON] (I have 0626 in CAID file & AUTO PMT [OFF])
Emulators [ON]
N2 AU [OFF] (although ON shouldn't make any diff)
Emu Priority [1:EMU, although 1:Cards shouldn't make any diff)
Fixed CW [ON] (as no dead CWs in my key.bin to mess with active Irdeto keys for InXWorld, but [OFF] again shouldn't make any diff)
