Troubleshooting

Try the fix for your problem below. If it doesn't help, ask on Discord with a screenshot.

Launcher and install#

Windows says "Windows protected your PC". Click More info, then Run anyway. The launcher isn't code-signed, so Windows warns about it.

The download is slow or stops. Close the launcher and open it again. It resumes where it stopped. Pausing other big downloads on your network helps.

"Virus detected", "files not found", "can't proceed", or the launcher disappeared. Your antivirus removed Eden files (a false alarm: the launcher isn't code-signed). Add your Eden folder as an antivirus exclusion, restore the files from Windows Security → Protection history → Allow on device, then sign in to the launcher and click Verify game files under Logout. Every click is in Installing & launching.

Files keep disappearing, or the game won't start. Same cause and fix as above.

The launcher says to keep it open. Leave it running while you play. It's carrying your connection to the server.

Starting the game#

The game looks frozen after I press Play. The first start loads a lot of data and can take a few minutes. Wait before closing it.

Stuck on "Connecting to server". Close the game and the launcher, then start again through the launcher. Check the server status at the top of this site. During updates the server is briefly offline.

The game closes right after login. Usually antivirus. See above, then Verify game files.

"Eden Anticheat" closed the game. It found a cheat tool, a debugger or a changed game file. Close the program it names (Cheat Engine, memory editors, debuggers), then start again through the launcher, which repairs changed files before the game starts. If it keeps happening without any such program, ask on Discord and include the message it showed.

The first start after an update takes a few minutes. Eden Anticheat checks every game file the first time. Later starts only check files that changed.

I was sent back to the login screen with an Eden Anticheat message. The server didn't hear from Eden Anticheat. Start the game through the launcher instead of MapleStory.exe, and don't close the small Eden Anticheat process while you play.

In game#

My skills stopped working. Type @check. It fixes most stuck-skill states.

A quest won't progress or complete. Type @check, then work through the steps in When a quest is stuck or broken. For Arcane River quests, @fixquest repairs the ones we know about.

I get "You can't repeat the same line" in chat. That's a client rule against spam: you can't send the same message four times in a row. Change the text a little.

My EXP suddenly dropped. Look for a rune on the map. An unused rune curses the map's EXP. See Runes.

The game lags in crowded maps. The client does most of its work on one CPU core, so very busy maps with lots of skill effects can slow it down. Closing other programs, lowering in-game effects and plugging in a laptop all help.

Auto Battle keeps stopping. Check the message in chat. Auto Battle (@ac) lists what each one means.
