Maybe you have Noscript or another Javascript blocker active in your browser? If so, try allowing the Freescale download page.
Also, I wonder if this upgrade is the same as the Compiler patch for CodeWarrior Development Studio for ColdFire V7.2.1 Build Tools that appears on this page? (The info button does not provide any details about a part number, unfortunately.) If so, try downloading it from there.
