The Logic Off Topic list

Hi All,
I recently purchased and installed the UAD-1 DSP Card and Studio Pak plugins, 
but is not working at all. The System profiler is not seeing it. I re-installed 2 more times 
using different card slots. I'll list my specs below. Has anyone here had the same problem?

much thanks, Tom
