Hmm.... well I THINK you're saying that you just clicked and dragged the add ons in one folder over to the other they didn't show up and now blockland doesn't work.... Well, I would suggest that you try re-downloading Blockland V10, and this time look at all the add ons in the file and click and drag them over one by one. It may be more time consuming, but it saves you a lot of trouble. I went through a problem like this, and the entire baseplate section disappeared.
