ReferenceError: Can't find variable: Check
Make sure you have the Util API installed (it should be the first thing included in your main script), it contains the Dependency Checking functionality that almost all APIs require.
The error will usually be detected within the C++ js_include() or loadPlayerScript() functions. The file named by the js_include() log entry will usually be the file that is trying to use Util API. The file named by loadPlayerScript() will usually be your main script, the place where Util API should have been included.
