Problem: you see a "raven-license.warning.evaluation.label" warning message
Solution:
Don't worry, the message you are getting is indeed annoying as it is not the correct one. This is the message that you should be getting:
This message is shown only during the evaluation of the product, and it does not represent any restrictions on the product features. So you have the full product and only getting this message during evaluation.
Those "codes" represent the actual messages and only are shown when the language resource files were not correctly installed. If you reinstall Xray, it will fix this problem, don't worry as no data will be lost during this process.
