There may be a misunderstanding. Ableton has an Intro version of their product Live, but we also have an Intro version of Videosync. At a reduced price (€ 79 at the time of writing), this gives you access to full video playback but not to using plugins, regardless of the Ableton Live license you own. So what you are seeing is expected based on the license you own.
If you are interested in using the Videosync plugins, you can consider purchasing a full license. Note that you can deactivate your license on your machine to test the plugins in demo mode without a purchase.
I closed my laptop and when I opened Ableton again to proceed I got this message
I’m not sure what could have caused this. I just tried entering a Videosync Intro code myself and as far as I can tell everything behaves as expected: the demo overlay disappears and the Videosync plugins switch to deactivated mode immediately.
Btw if you do decide to go for the full version, please let us know. We will then send you a coupon code to reduce the full license price to € 120 since you already purchased Videosync Intro.
