I went and bought every single thing needed for my character. I went to export in FBX and it gave me this message with a prompt to "buy" something. I went and bought that something but im still getting this message. Any help? Images below



This is the thing that the buy page has prompted. As you can see I already bought and have this item installed.

Only way to bypass it was to delete the hair. I guess i'll just have to cope with doing the hair again. 

Had same issue, I ended up un-installing it and re-installing using the smart content tool

I also had same problems...
Though there is an easy fix, simply go to "help" and click "activate purchased items".
Should work in most cases...
