To help you with the problem we might need just a little bit more info.
- What doesn't work in your Obsidian mod
- Does nothing work or don't you get 'mine-toon' images (As far as I can see the minetoon supports 'only' textures for the bucket, default and legacy mods) or
- can't you create a world anymore
- did you succesfully install other texture packs before
- Did/does the Obsidian mod work for you before you used/without using Minetoon (I didn't try, but maybe the mod isn't up to date anymore EDIT:http://minetest.net/forum/viewtopic.php?pid=46945#p46945 --> Looks like it still works)
- Did/does Minetoon work for you before you installed/when you uninstall the Obsidian mod
You read the warning in the first post of Minetoon?
