RuneScape stores some files locally on your device. Sometimes one or more of these files can become corrupted and cause problems starting the game, clearing your cache will force these files to redownload.
Once you've cleared your cache you'll see a progress bar below the lobby. Wait for your cache to reach 100% before playing.
