This is very strange but I had the same problem the very first time I upgraded from 4.23 to 4.5 and updated the drivers for the DSP. The second time I completely removed DSP drivers and Logic (I only kept my autoload) and cleared out the registry of all Logic entries and then installed Logic again from scratch, gradually updating up to 4.5. I then reinstalled the DSP drivers AND ran the driver ASIO setup in the ASIO subfolder and it worked fine after that. Phil Keyboard not found... Press F10 to continue...
