WaveHC - SD Card read stalls out

Hello everyone! So I've got my wave shield on top of an ethernet shield on top of my uno. Quite the stack! I've tweaked the ArduinhoPins.h in the library to make the slave select use pin 9 so the ethernet and audio shields can play nice. But i've run into a problem.

When I run the daphc example, I don't get an error in my serial read, it just stops working. Always at the same point, too. Turning on hidden files to manually delete the offending directory did nothing either.

Wave test!
Free RAM: 669
Using partition 1, type is FAT16
Files found (* = fragmented):
~1.TRA  
TRASHE~1/
  501/
    STORE-V2/
      AF33F5~1/
        PSID.DB  
        TM~1.SNO  
        TM~1.LIO  
        LIO~1.CRE  
        INDEXS~1  
        ~1.IND  
        ~~2.IND

There's where it stops. Nothing special from the waveHC example has been altered. Any thoughts?
