Troubleshoot license errors in GameDriver
Issue
The "GDIO LICENSE ERROR" message occurs when your license file (gdio.license.txt) is either missing from the Assets\GDIO\Resources folder or invalid/expired. It will appear in the agent overlay:
As well as the console or player.log upon startup:
Invalid or expired license @ Resource gdio.license
UnityEngine.Debug:LogError (object)
gdio.unity_agent.GDIOAgent:Awake ()
Solution
Check that your license is valid, and located in the Assets\GDIO\Resources folder of your Unity project.
