@CivFuehrer: I was thinking about some requirement too but there should be none; AFAIK, MAD civic is the only requirement; I've also built manhattan project and missile Lab to produce ICBMs and of course I have Uranium. So unless there's some other requirement that I don't know of, there's no reason it shouldn't work... but it doesn't.
As for getting to modern times, I've only made it once, playing with AND 1.75A and as described here, Mad Nukes Panel didn't work either:

I've tried some different combinations of map sizes and civs and I've almost never reached the modern era, let alone finishing the game; I've never been able to. I've tried with some GEM but I usually get CTDs before the modern era; then I switched to some Huge Earth map but playing with 20-30 civs always ends in CTDs; I usually play with my wife in hotseat mp, using almost all expansions provided on the custom game menu (adv dipl, adv esp, exp castle, guilds, corps, adv nukes, etc. and of course Revolution, No barb civs). Now we're trying a huge map with 18 civs, no megacivpack and we hope it will work. But I say again, I've never ever been able to finish a game with RoM-AND due to CTD. I suppose my pc is good enough (Q9450, 4GB ram, win7 64bit, 1GB video card), so my guess is that CTDs are caused by limitations of the Civ4 BTS engine.
@Afforess: thanks, that would be great, maybe it's just me missing some requirement as CivFuehrer said, but as I said to him, even with AND 1.75A MAD Nukes Panel didn't work, as explained here
