client out of date?

[jettle]

Had issues with the new spell file patch. Restarted computer and now its telling me at server select that i have an outdated client. I feel like this is a simple issue but i am by no means a computer tech guy so its beyond me. Im sure this same topic has been posted a thousand times but i didnt see much on it unless i over looked it....should i try a reinstall of duxas?
