Rigify button not working (greyed out)

So I import the character I just exported from AccuRig to blender, but when I try to press the rigify button is all greyed out.
I tried using different version of Blender but nothing seems to work.
Any help?

Hi woodyinhogfx,

Could you please let us know your current versions of the Blender Pipeline and Plugin ?

Also, please confirm your Blender and Character Creator versions. This will help us identify the cause of the issue.

Thank you for your cooperation.
