Whoo! So, I finally got the Delta to work... It involved uninstalling, removing PCI cards, changing the PCI slot I was plugging the Delta into, reinstalling, etc... But it works!
Now, I just need to get Cubase up and running. I installed it, but everytime I try to open it, I get an error message telling me a file is missing. I did have a little wierdness when installing, so I may need to reformat and try again, but I think I'll get that figured out a lot faster than I did the Delta.
Thank you so much to all the people who gave advice and offered help! HG, D, and KSG, I'm looking at you! You guys rock! : )
