I am closing this thread now.
The MV 20-day trial is available on the Product page for anyone who didn't preorder and wants to get it now.
The extra resources (including plugins) are in separate folders under DLC or with the download. You need to copy them into your project before you can use them.
The "surprise" resources that were removed due to being unsuitable for a younger audience, should you want them, will be available in a little while - we just want to reorganize the folder structure. No need to PM anyone - when they're available, we'll let you know.
Other "how do I ..." and "where is ..." questions can all go to the MV Support forum now. PLEASE look through to see if your question has already been asked, as we are getting several popping up frequently. If you need help with plugins, there's a JS Support folder in the scripting section.
