Hi all, I keep getting this error after I click play runescape in swiftkit. java.io.IOException: Invalid keystore format. I have absolutely no idea what it means but I would like some help understanding and to try and correct this problem. Thanks in advance.

Sounds to me like your Java install is corrupted I would try re installing it.

ok I uninstalled Java and re-installed both 32 and 64 bit, and i still have this problem, i also tried using an old Java ver 6 update 37 I think and that still had the same effect. This is what came up for me.
