Since I deal mainly with computer hardware a lot and not software, this is a bit of a foreign language to me.

Whoever can translate this gibberish, it will be greatly appreciated.

Thank you.

Sorry to revive necro post, but this is exactly what is happening to me.
I haven't logs like OP, but I notice the behavior is on 64-bit windows. Tried on 32-bit windows and problem goes away.
I've done clean install of both OS and FFXI software and problem persists (I use the installers from the Abyssea Collection digital download).
I've tested on two computers, one was Core 2 Duo/GeForce 9800M GTS and the other was AMD A6-5200 with Radeon 8400 graphics, both on newest 64 bit drivers. Both systems have 4 GB of RAM and 750 GB Western Digital Scorpio Blue hard drives.

The problem appears to be most common after lengthy play sessions and while acquiring sparks of eminence. First sound effects start lowering in volume, then finally disappear completely, then, as OP mentioned, character movement animations stop loading correctly.

Once sounds start lowering in volume, any change in zone will cause a POL crash, so will minimizing the window. I haven't tested in full screen.

No other games are installed on the computer, sometimes Internet Explorer is running in the background and sometimes along with Flash Player, and Windows Aero is always enabled.
