Common problems
Terrain Control doesn't always work like how you would expect it. On this page some frequent problems are highlighted. If you're still stuck, create a forum topic that describes your problem. Be as detailed as possible and be prepared to post your startup log (preferably on pastebin.com) or your settings (preferably in a ZIP).
Terrain Control won't take over all your worlds when you install it. You'll need to enable it first. Closely follow the installation instructions. When you're still stuck, it is important to post yoyr startup logs when you are creating a forum topic.
Have you tried regenerating the terrain? If yes, move your TerrainControl folder, start the server/the game again and look whether Terrain Control has remade the settings files. If no, then Terrain Control is not even reading them. See the problem above this one on how to solve that. If yes, look at the BiomeMode and TerrainMode and make sure that they aren't set to Default (which makes them ignore your settings and use the vanilla settings instead).
Don't worry, it is there. Keep swimming. Alternatively, you can change the seed of the map (for servers: you'll need a new level.dat for this, changing it only in the server.properies isn't enough) to something else. The seed 11 will spawn you on land with the default settings. You can also disable or reduce the oceans using the LandRarity setting in the WorldConfig:
Most settings are case sensitive and whitespace sensitive, so be precise. Some settings need higher values to give a noticeable effect. Other settings need the Terrain Control client (see the comments in the files and/or this wiki). Some settings are dependant on another setting (again, see the comments in the files and/or this wiki).
If you are not experienced with Terrain Control, always make sure that SettingsMode is set to WriteAll. This will make Terrain Ontrol reset or remove everything it doesn't understand, so that you'll immediatly notice that something was wrong.
