Theme forest for vBulletin 5.7.2 Issue on installation

Hi everyone, I bought a Themeforest Metro for vBulletin 5.7.2 and I’m having issue when I try to install it. There anything missing on the files? How can I fix the kind issue? Thanks anyone for helping with that.
This is the message that I got:

“Sorry, you don’t have permission to upload styles that include templates that are not textonly. Please make sure the XML you are uploading has no “templategroup” tags, or that any defined templates have the textonly attribute set.”

How can I fix that? :thinking:
