Launching Problems Start-up Fix
The Problem
MapleStory is a wonderful game, In my opinion that is. A couple months ago I decided I would come back to MapleStory and play it again. Downloading the game was fine. I didn't run into any problems that way. I started up the game and on the bottom right corner I saw the Nexon Game Security sign pop up for a good 30 seconds. Then the whole game would disappear. I thought, "Well this is the first time the game is running.. Probably just a test or something."

I clicked play again. Same problem occured. So I decided to open task manager up and went looking for the game. There was NO sign of the game running. I clicked play once again and had task manager up and watched the process it went through. Once again the game completely closed out. I thought, "Well I'll come back to it a different day and see if anything changes.
So I came back about 2 days later still not working. I wasn't happy that I couldn't play a childhood game. So I contacted Nexon Support. The person who helped me wasnt much help. It was the typical questions..
Did you re-download the game?
Did you re-download the launcher?
Is your internet working correctly?
Did you restart your computer?
I tried all of that.. The guy walked me through something where I couldn't even open Steam anymore. I redid the whole process so I could use Steam again. I went searching in Steam to see a good amount of people were having the same problems I am. I found no-one had solutions. So I did some research. YouTube and Google can be your friend sometimes...

The Solution
