  • Pixelmon requires Forge and is only compatible with Minecraft 1.6.4

  • Here are some steps you should try.

    1. Make sure you have the right version of forge.
    2. Make sure you have the right version of the mod.
    3. Make sure you have installed the mod properly (watch a YouTube video)
    4. Try a different version of Minecraft

    As it is a "NoClassDefFoundError" this suggests that the mod isn't installed properly as it is searching for a .class file that isn't there or in a different directory.
