TerrainControl v2.8.1-SNAPSHOT is for Minecraft 1.9.4, and you are running Minecraft 1.8.8. Download an older version of TerrainControl from here.

i have tried the 1.8.8 version and it does the same thing kid.

Un thoughtful memories shall not make me fear things!

Make sure you have overwritten the other TerrainControl file.

It would also help if you post the error you are currently getting. If it's the same, line for line, as the one above, then we know for sure that the other TerrainControl file is still around, and you'll need to overwrite that with the one I linked.
