I am getting an error message when opening xLights, Unable to load network file. Then I press (OK) and the next error message is XML parsing error:unclosed token at line 2976. Then when xLights open up my network settings are blank. I have tried a number of different options including reinstalling xLights, Copied the network file from a backup that I had before this issues and still getting the same error. How can I resolve this and get my network settings back?
