Type Error... Any help?...

This Error appears when i hit the menu button in game, but eh game plays fine otherwise...

First, please remove all non-network-letters from any of your directory names and filenames - for example spaces are not allowed under networking rules, which is why they get replaced by %20 in those error messages.
That will probably not remove this specific error, but it will prevent future errors.

Second, does this happen if you start a new game in your project or only when you load a saved file?
After adding new plugins, you have to start a new game or get errors like undefineds and type errors.

Third, it might be an incompatibility between two plugins or simply the wrong order of plugins - we need to see screenshots of your plugin manager to determine that.
