I'm using usb..followed instructions from the site. I believe the hardware installation is the problem....the computer I'm using doesn't like the 990 software and let's me know it every time I try installing it. "Inf" domain errors, etc...I'm only using this old computer because it has Xp and my laptop uses win7..It could be the computer, it could be the 990 itself. I've given up on contacting outlaw for any help.....the good news is that I didn't turn the 990 into a 28 lb. paperweight. For now I'll return the old computer and be glad I came out even. Thank you for your reply.
