Maplestory Error

^useless post is useless.
Anyway, I've had the same problem.
Restart your computer.
If that doesn't work, run Maplestory through the website once, if it works, it's not a server check.
Exit Maple, and try again.
If it fails, turn off your firewall (Temporarily!)
Log in, if it works, you have your problem.
Turn it back on, navigate to your firewall settings, and allow maplestory to pass.
If the firewall didn't fix it, you probably have a internet blockage or something.

hmm what I said didnt work or what other people said. Just try re downloading.
