Give access to some users manually

Hi,

I installed this plugin on a client’s site. He used a different way to sell access to his videos before (which didn’t really work) so I used this instead. Now there are customers who have already purchased access to the videos and I want to update their accounts manually to have access to the videos they paid for. How can I do this?

Thank you.
