CI2 Driver Problem in Cubase 7.5 64Bit

Yes, I have Windows 7 Service Pack 1 and I am using Tools Version 1.8.3 And yes, I have it plugged in before I start Cubase. The strange thing is, I just set this all up on my Laptop running the exact same OS and it all works beautifully. I’m at a complete loss. Totally stumped.
