I upgraded to leopard and quickly found out my audio interface (m audio mobilepre) wasn't compatible. I downgraded to Tiger to wait for driver updates. M audio just released driver updates and now i have upgraded to Leopard once again.
I updated drivers and i still cannot use my mobilepre with Logic Pro 8 or Garageband. I am not sure what else to do. Anyone have any ideas? I have tried uninstalling and re-installing drivers, but that hasn't helped. I have noticed that it crashes at the "initializing core audio" screen. I also unplugged my audio interface and LP8 still crashed.
Thanks
edit: i figured it out, there was a plug-in in the Propellerheads ReWire folder that was old. I erased it and LP8 started right up!
