Problems installing game updates

Im having problems installing the game updates. I began to instal one, but when it finnished i accidently opened the launcher too early and it cancelled it. When i tried to reload the update, when it finnished loading it told me it could not complete the update because i needed to finnish installing the first cancelled one before it could install that second one i tried to instal. which im pretty sure was the same update.

Any ideas?

ps. i have the sims supernatural expansion if that means anything
