When you start the software I'd expect it to say that you are running a trial. Click License this Software or something similar.

I assume it was installed as a Trial.  Under the "Help" menu, select "Repair Acrobat Installation." It will tell you it is in trial mode and how many days are left. From here, you may click the button to license the product.  You will be prompted to Sign In to the adobe Web site and enter your serial number.  It seems to consistently work if entered this way.
