When the program is opened, swiftkit freezes at the opening screen (the opening window is opened, then freezes, before the Click to play button appears).
It seems that the program is freezing when loading something.
I have tried deleting existing swiftkit program files and re-installing, and updating java, and deleting all runescape files. Nothing is working. It truly seems that, since today, swiftkit is not able to be run anymore.
