Danny,
Sorry that you are seeing this error.
1. Where exactly are you seeing this error? Possible that the .codemix.properties file which is located in your user home directory has an invalid or expired activation data from a previous expired license.
2. How did you activate the CodeMix license in your machine? From our records, I see you have a CodeMix personal license without the key.
You can go to Help > CodeMix > Update License dialog, login using the user id : dannysu and click on ‘Check Access’ to unlock the Personal license.
If you are still seeing the error, then delete the .codemix.properties file, restart the IDE, go to Update License dialog, login using your credentials and click on ‘Check Access’ to enable the latest license.
Hope this helps. Please let us know how it works for you.
