I have Razer Cortex installed as well as the desktop shortcut for Old School Runescape. I have attempted to add it manually to Razer Cortex, but it keeps saying it is unable to load the parameter file and to reinstall the game. I am playing on an old Dell laptop (inspiron, i believe) and the OSRS is able to load up through the desk top. Is this particular Runescape version compatible with Cortex? If so, how do I fix it to where it works on Cortex?
