ok ty
not working but thanks for the help anyways man
If you can't open 2 clients at once there is something wrong with the game routing its connection.
Jagex allows you to run 2 clients at once Maximum. I would recommend uninstalling OSRS and reinstalling it.
After you reinstall, Put it on your desktop and login to RuneMate, After you login to RuneMate Launch the Clients from your DESKTOP.
When you launch them you want to click 3-4 times, Hell if your PC can handle some power spam click the Launcher. Either way you will get two or more to load. If not you want to reset your router and modem even further, It's just a connection stringing issue Because anybody can run 2 OSRS Clients
