I am running 2025.12.1 xLights. I cannot access settings or model preview, among other things. I tried to resolve in chatgpt. It says I am running xLights sequencer and not the full xLights. I never had this prior with the previous versions of xLights; this is my third year. Am I not running xLights properly? How do I resolve? Chatgpt told me to delete xlights and reinstall but i dont want to lose everything and start anew. Any suggestiong?
