Whenever I try to try and buy membership, I have to log in again. When I log in, I get this error, no matter the browser I use:
I have cleared the cache and cookies for all sites related to Runescape, I've even fully cleared my history, browser, cache, etc for all time, including all other sites.
I really wanna get back into the game, and not being able to buy membership is putting me off a bit.
Does anyone know how to fix this?
