I had an issue where the client launcher wasn't saving the settings. Solved this by setting the settings, clicking OK then killing the launcher with the X button at the top right of the window. Reloading then seems to have called up the info I saved... well some of it, it managed to find the default font and resolution that would normally be there and set it accordingly (which is different to what I saved).
Now, I can't change the skin it's using, it's locked to default. I click on 'change' and it flashes as though a window should come up then nothing. more clicks produce nothing.
Can change every other option instantly now except the skin, which is a pain a$$ I dislike the original and my interface is now all over the place!!
Going to keep trying things, anyone know if there is a single file which holds all the setting info so I can delete it and start again?
