Register theme to update slider plugin

Hey everyone.

Not sure if this is the right place to ask this, but I manage my own wordpress site. (Content, updates, etc.) However, I didn’t design my site. I had a friend who does web development do that because he knows that all much better than myself. (I do video and animation)

The slider revolution on my website doesn’t play or it freezes sometimes on other computers and I concluded that it should be updated. Now, when I go to update the plug-in, it says I need to register my theme with a purchase code. He’s the one that decided to use Slider Revolution, but didn’t purchase a license…so, I don’t have a code to update it. Should he be the one updating it or should I just bite the bullet and buy the license myself since I update the plugin since I manage my own site’s content and updates?

Thanks in advance!
