It may already be working, just not showing up as active. If you have 2004 or 2006 check to see if either of those versions show that the FCT has been activated.
I had the same problem. It took over 24 hours for the activation to actually show in CM2 however when I downloaded assets using CM2 it was apparent that it had indeed been activated.
Try and download something and see what speeds you are achieving. You may have the same situation.
