I don't understand how it went wrong! I updated Java, and once I tried to get into the game, the game's shortcut and installation has been identified as "invalid" & has an "expired or not-yet-valid certificate", and no matter what I try, it always does the same! Even the game's shortcut installation has been mistaken as "corrupt or invalid", & the only reason it stated was this: "Your security settings have blocked an application signed with an expired or not-yet-valid certificate from running", but the game's shortcut doesn't have a virus or something!
