My launcher opens, but I just get "A connection error has occurred. Please try again later." My friends who play are not having any issues.
Have tried restarting my PC and internet connection, reinstalling, downloading the windows version of the launcher (as I usually run it through steam), and all are getting this issue, as well as all the stuff usually suggested in the FAQ type thing.
