Yes... It made no difference, As I said before...
I've merged my OSRS account...
It even says on the Jagex Warning before doing it, that you will no longer be able to use other launchers except for RuneLite, as theyre not supported yet.
I don't think you've properly merged your osrs and Jagex Launcher account, because if you've imported your character from OSRS to the Jagex Launcher website, It gives you a warning telling you that you can't use the old RS client, or anything else, you have to use the Jagex Launcher
Where you get the "play" button and not the username / password
Yes ^ The new "Open Beta" crap, I was prompted to click it when i checked my mute status. T_T
Is there anyway around that?
