Problem with revision 2953?

I've been having a lot of trouble trying to get Super Smash Bros Melee to run on this version. When I open the emulator, it gives no errors, but revision 2195 says I'm missing my DirectX, however, it was just installed.
I turned on dual-core, which eliminated my "Failed to grad 1GB of contiguous memory!" error, but it still crashes with "The instruction at "0x0cc3001f" referenced memory at "0x0000522c". The memory could not be "read"." :dead:

Windows XP Professional, SP3
Intel Pentium 4 (Dual core? My computer lists two), 3.01 Ghz
nVidia GeForce 7600GT
1.00 GB of RAM
DirectX 9: March 2009 Runtime

Note: Dolphin v1.02 runs fine, just super slow. It's outdated, so I would love to be able to use the new versions. Sorry if this has been fixed elsewhere, but I haven't been able to find the answer I'm looking for.
