MapleStory Not Working...

Okay, so when I start MapleStory, it comes in the regular window, where the whole bottom screen is covered by a rectangular thing that says PLAY instead of it being in the corner. When I press it though, it takes me to a PATCH window, and when it say it's done, it leads me into a website. Should I re-download the whole MS again?

Redownloading MS is always a good idea to try to fix a problem. Other than that, I've never heard of such a problem.

Is the play button blue? If it is you might have an outdated version of MS and it cannot patch up anymore. Just a thought :S
