Logic Express 7 + 2 Firepods, Logic Express defaults to built in audio.

Title pretty much says it all. I set up the 2 Firepods in MIDI Setup using Device Aggregate Device Setup and I have run the setup assistant in Logic Express for that new device, I select 12 inputs and 12 outputs.

When Logic Express opens I get the message:

"The previously selected audio interface is not available.
The built-in audio inputs and outputs of the computer will be used instead for this session."

I am able to output through the Firepods no problem in anything else, and I am able to record 16 channels in Audacity no problem.

Does any one have any idea's or suggestions on how to get this issue resolved?

 

I have 2 firepods set up in OS X for 16in/16out.

I have got it working now, I just had to play with the IO buffer in the CoreAudio settings in Logic Express.
