There is a DATA.BIN in the 158 rar file. After updating do you need to copy this file over to the CAM as well?
Wouldn't do any harm if you did. UnderWorld157 is working fine on 16E DigitAlb, 13E SexView, 13E NTV (RTVi), 19.2E MTV Unlimited, 0.8W/1W Canal Dig & 8W KabelKiosk (note SSN Supersport Networks is also broadcast in Conax on 12.5W & 8W and Diablo opens both - thx dxdy, good spot!), 7E HD, plus all the public hacks with this new data.bin (22/1) so I haven't used UW158 myself yet.
