The following is a collection of error messages or other hiccups some people commonly come across while using First Person Exploration Kit.Table of Contents
This error is most likely the result of the import of a conflicting asset package, probably the Standard Assets package. To fix, simply re-import First Person Exploration Kit or start a new Unity project and only import First Person Exploration Kit, and the issue should resolve itself. The reason this happens is that sometimes Unity thinks the First Person FPS Controller that comes with Standard Assets is the same as the FPEKit namespace FPEFirstPersonController and overwrites it without clear warning.
If you want to import the Standard Assets package (or another package that caused the import conflict), you can still do so. Just be sure to un-check the "FirstPersonExplorationKit" checkbox when importing Standard Assets, and the rest of Standard Assets will import as expected and First Person Exploration Kit will continue to work as it did before.
