I just Purchased the “Spring” Plugin, when I went to Register it, It is not on the select list of Plugins to register… Oh the Humanity… Can we get that on the list, have a couple of Surf tunes waiting…
This problem should be fixed already. Make sure you're clicking My Account -> Register a New Product and then selecting "Native Plug-in" as the category and "Spring" as the product. If you're still having trouble you can email support@eventide.com to get direct assistance.
