Can't download Adobe After Effects?

Copying a solution from the doc Troubleshoot Adobe Download Assistant (http://kb2.adobe.com/cps/898/cpsid_89867.html)

1. Clear your browser's cookies. If you don't know how, see your browser's documentation for instructions.
2. Go back to the Adobe Downloads page for the product trial you are downloading and refresh it (Command+R or Ctrl+R).
3. Click the Download button again to launch the ADA.
4. If the download does not start, verify your network connection and try again.
5. If your network connection works normally and you still get an error message after a few attempts, delete the contents of the ADA Local Store folder (Windows) or the ADA Preferences and Cache (Mac OS):

• Windows XP: C:\Documents and Settings\[user]\Application Data\com.adobe.downloadassistant.AdobeDownloadAssistant\Local Store
• Windows 7 and Vista:  C:\Users\[login]\AppData\Roaming\com.adobe.downloadassistant.AdobeDownloadAssistant\Local Store 
• Mac OS: /[user name]/Library/Preferences/com.adobe.downloadassistant.AdobeDownloadAssistant and /[user name]/Library/Caches/com.adobe.downloadassistant.AdobeDownloadAssistant 
   
  Tip: On Mac OS Lion, press Option and click the Go menu to reveal the hidden user Library folder.

6. Launch the ADA and accept the license agreement.
7. Close the ADA and repeat steps 2 and 3.
8. If the issue is still unresolved, check to make sure all anti-virus and firewall software is temporarily disabled on your computer.
9. Close the ADA and repeat steps 2 and 3.
