    See if there are error messages:
    Open a command prompt window and entry:
    java -jar THEJARFILENAME.jar

    copy the full contents of the window and paste here.

    On windows: To copy the contents of the command prompt window:
    Click on Icon in upper left corner
    Select Edit
    Select 'Select All' - The selection will show
    Click in upper left again
    Select Edit and click 'Copy'

    Paste here.

    You need to be in the folder with the jar file. Change the directory or copy the jar file to the Greg folder.
    The java command did not find the jar file.

    java.lang.UnsatisfiedLinkError: no lwjgl in java.library.path
    Looks like you are missing some parts. See the API doc for the class: UnsatisfiedLinkError

    I'm not familiar with lwjgl. Read its API doc to see where you need to place the parts it uses during execution.

    Do a google with java.library.path for info on the problem and its solution.
