I installed the recommended version of Forge in order to play the TekTopia mod. It was working fine. Then my daughter wanted to use the Biomes of Plenty mod and installed another version of Forge, which seems to overwrite the one I installed. Now, Tektopia is no longer listed as a mod, even though it is in the mods folder. I tried uninstalling all of the files for both Forge and all the mods. I even uninstalled Minecraft & reinstalled it, and the launcher still lists Forge under "installations." However, now when I try to play it, it says it cannot load the game. I've tried reinstalling it several times. When I go into options for the Forge installation, there is no "delete" option...only edit and duplicate. Please help!
