| Problem | What to do |
| Windows SmartScreen blocks the launcher | Click "More info" and then "Run anyway". The client is not signed with a commercial certificate. |
| The client opens and closes immediately, or shows a black screen | Try otclient_gl.exe (OpenGL) instead of the DirectX build, and update your graphics driver. |
| "Connection refused" or "Server offline" | Check the server status on the home page. If the server is online, a firewall or antivirus may be blocking the client: allow otclient_dx.exe. |
| Wrong password after creating the account | The account is identified by the account number, not by e-mail. Passwords are case sensitive. |
| Client stuck on "Updating" | Delete the extracted folder and extract the .zip again. |
| The client never updates (old logo, old login screen) | Your copy is from an older address and cannot reach the update server any more. Download the .zip above once; from then on updates are automatic again. |
| You moved the files out of the folder | Keep otclient_dx.exe next to data.zip. The client only updates itself when it runs from that package. |
