Counterfeit?!

Midway through installing my CS6 web premium, Student and Teacher edition, the disc was spit out along with a message saying the software appears to be counterfeit. I just perchased it from Amazon new for 450 ish dollars! The box and packaging all seemed very legit, including the whole verification process I had to undergo to use the software. I tried installing it TWICE, each time the same message popped up, rejecting the dic.

It said to contact support, and led me roughly here.

What should I do?
