Does it eventually close the whole folder and program?
If so, then something in your folder is corrupt.
Try redownloading the v88 folder
hereand also try redownloading the update and launcher as well
hereThen try these to get the game up
First, download
THISThere should be 2 things in there: SoulMS.exe and HSUpdate.
What you do is put the SoulMS.exe into your maplestory folder where your maplestory.exe is
Then you put the HSUpdate into your HShield folder in your Maplestory folder and replace the one already existing in there.
After that, you should open SoulMS.exe, type in your ID and PW then click settings go into your v88 folder and select maplestory.exe (NOT SoulMS.exe)
Then check off 'Launch Maplestory automatically' and save changes.
Then click login and it should open up a browser (http://soulms.net/fixhs/)
Then just [x] it out and [x] out the popup that also says "Download HSUpdate.exe & extract it in your GMSv88 folder."
Now, the launcher should pop up.
Click Game Start and hopefully HShield will run and you'll be able to log on.
Hope this helped
Good luck~
