Disgaea 3: Absence of Justice [BLUS30181]

I so want to play this game on pc and have been trying for hours. I can get it to the now loading, but the tty text just shows this:

********************************************************
NisAnmInit()
********************************************************
* NisMovie_Play: ERROR! exit. (ret=0x80610003, file=NisLib/NisMovie.cpp:956)

These are the errors I get:
E LDR: Unknown function '0x05893E7C' in module 'cellLibprof' (index 3003)
E LDR: Unknown function '0x6D045C2E' in module 'cellLibprof' (index 3004)
E LDR: Unknown function '0x9FB6228E' in module 'sysPrxForUser' (index 3005)

E {SPU[0x2000007] Thread (_libdmux_pamfCellSpursKernel0)} SPU: [0x08d7c] Branch-to-next with $LR

I've tried with the bare bones sprx's listed here, the ones in the bug reply that raven posted and other combinations. Do sprx vs prx matter? What are these .elf files that raven posted about?

I'm also on win7 64 and using opengl (though, trying vulcan also got stuck on the now loading portion). Updated to the latest nvidia drivers. Running on 8gb of ram, on an AMD FX 6200, NVidia 750TI

Please help and thanks in advance!
