Hey,
Sorry that you are seeing this problem.
Can you please shut down the IDE, delete the engine folder which is located in the .codemix folder in your user home directory, restart the IDE and see if it fixes the problem? On restart, the engine will be freshly extracted.
If you are still seeing problems, reboot your machine and check. If none of the suggestions help, then please reach us via Live Chat ( Help > CodeMix > Live Chat) to help us quickly diagnose the problem.
Apologies for inconvenience caused. Please let us know how you get on with this issue.
