The current version of CS is 6 not 6.5 At the end of December you will loose the ability to upgrade to version 6. You need to call Customer Service to do a cross grade from CS 3 Windows to CS 6 for Mac.

What Michael said.

You have until 31 Dec 2012 to upgrade from CS3 to CS6 (or in your case "crossgrade").
