Then... toward the BOTTOM RIGHT of the page you will see a link that says, "AEM Forms Designer - 1139-1001-3886-4854-1284-1828"
Click on that link to download AEM Forms Designer. Then when it prompts you for your license key... use your original one from LiveCycle Designer ES. It will download (using WinZip). And VOILA! You'll be up and running in about 5 minutes ! Good Luck !
