Gave it a shot... the error you got is basically saying the computer ran out of RAM!

Same thing happened to me, too. You must of had a lot going on in that game. I didn't try lowering the graphics settings... although that shouldn't matter since most graphics cards (including mine) have a GPU that processes these things seperately.
I'll search the forums and see if there are any recommendations on what to do if you run out of RAM while playing late in the game...
Is the change to Holy Cities recent where you don't get the benefits unless that religion is your current religion? Had a couple of religions founded and holy cities with the requisite great prophet building, but didn't get any benefit? I noticed that different religions now provide different benefits (Jewish is espionage, Christian is gold, etc....not a fan of this change by the way) too.

Ah, is that the way it works? Does this mean that holy cities are useless when you run the Pacificm civic (or for any other reason don't have a state religion)? This could explain my problem, as I wrote earlier in this thread:
Pacificm has a State Religion. The only one that doesn't allow a State Religion is Free Religion. The rest (Organized Religion, Theocracy, Pacificm) allow them.
Here is how the vanilla religions look:
Code:
<GlobalReligionCommerces>
<iGlobalReligionCommerce>1</iGlobalReligionCommerce>
<iGlobalReligionCommerce>0</iGlobalReligionCommerce>
<iGlobalReligionCommerce>0</iGlobalReligionCommerce>
</GlobalReligionCommerces>
<HolyCityCommerces>
<iHolyCityCommerce>0</iHolyCityCommerce>
<iHolyCityCommerce>0</iHolyCityCommerce>
<iHolyCityCommerce>4</iHolyCityCommerce>
</HolyCityCommerces>
<StateReligionCommerces>
<iStateReligionCommerce>0</iStateReligionCommerce>
<iStateReligionCommerce>0</iStateReligionCommerce>
<iStateReligionCommerce>1</iStateReligionCommerce>
</StateReligionCommerces>
<GlobalReligionCommerce> Increases the gold, beakers, culture, and espionage per turn for the religion's shrine by this amount.
<iHolyCityCommerce> Increases the gold, beakers, and culture, and espionage per turn in the Holy City by this amount.
<iStateReligionCommerce> Increases the gold, beakers, and culture per turn in the religion's cities by this amount if the state religion is present in the city.
So in other words, in vanilla civ: all the religions give +1

to the Holy Shrine (if built), each religion gives each Holy City a +4

boost, and each city with the State

present in it gets +1

.
Here is Judaism for History in the Making:
Code:
<GlobalReligionCommerces>
<iGlobalReligionCommerce>1</iGlobalReligionCommerce>
<iGlobalReligionCommerce>0</iGlobalReligionCommerce>
<iGlobalReligionCommerce>0</iGlobalReligionCommerce>
</GlobalReligionCommerces>
<HolyCityCommerces>
<iHolyCityCommerce>0</iHolyCityCommerce>
<iHolyCityCommerce>0</iHolyCityCommerce>
<iHolyCityCommerce>5</iHolyCityCommerce>
</HolyCityCommerces>
<StateReligionCommerces>
<iStateReligionCommerce>0</iStateReligionCommerce>
<iStateReligionCommerce>0</iStateReligionCommerce>
<iStateReligionCommerce>1</iStateReligionCommerce>
<iStateReligionCommerce>1</iStateReligionCommerce>
</StateReligionCommerces>
Basically it's the same as vanilla, except I'm giving you +1 extra

in your Holy City, and +1

(in addition to +1

) if Judaism is your State Religion and it's present in your cities.
That's how it works.
