Junan,
Sorry that you are seeing problems with CodeMix.
If you have installed CodeMix successfully and seeing problems with the engine startup, then please shutdown Eclipse, delete the .codemix/engine folder located in your user home folder and restart Eclipse. This will extract the engine again.
If the above suggestion does not help, then please reach us via Live Chat (Help > CodeMix > Live Chat) to help us diagnose the problem.
Please let us know how this works.
