Hi Mike,You can find the Content Wizard from the link below. This link is working ok.

I'm not sure why the Comic Character Specimen link isn't working either but you should be able to login to your account and download it from there. Download links for purchased software and packs are listed in your account. Have a look and see if you can download it that way.
If you still have problems downloading then please contact support who will be able to help you with this. Please use the form linked below to contact support.
