The site hasn't changed at all, I do own the license on the site. I do not know where to find the loader or guides the page looks the same as I am signed out.
If you need help finding the loader button on the site I would join discord or follow injector download. Easier to support you on the actual site than wait a day for replies from you here.
And guessing you used the same account name. You have access. All you do is click loader.
