    Scan your PC for malware.

    You don't need to scan your PC for malware. This is happening for everyone on PC, I'm not sure about consoles. If you look on the page it says in bold red letters. "Status: 1/21/2017 11:24 PST - We are currently investigating an issue with logging into the game."

    Hello, Sorry to hear you run into trouble.

    Do you still run into troubles?

    If LaunchPad continuously downloads the same files every time you launch, the following are a few steps you can take.


    Right-click on the LaunchPad icon and select "Run as Administrator" to load it with full access. Log in and enter the game as you would normally.

    Conflicting Software

    The following programs are not legitimate anti-virus software and have been known to cause issues with the LaunchPad. These are non essential programs that may adversely affect computer performance. None of these programs are necessary to run Windows.
    • Browser Safeguard
    • Browser Infrastructure Helper
    • Search Protect
    • Browser Defender
    Browser Toolbars

    In addition, some browser toolbars (such as Google Toolbar or Yahoo! Toolbar) provide popup-blocking that can cause connection problems while using LaunchPad. It is recommended that you uninstall them, reboot the machine, and then re-launch the game. These can also effect game performance and hinder the connection to the game servers.
    Reset your Internet Options

    Even if you use Firefox, Google Chrome or another web browser to surf the internet, the LaunchPad runs off of Internet Explorer settings. Follow these steps to reset your Internet Options which may improve LaunchPad performance.
    1. Go to Start, then your Control Panel.
    2. Click on Internet Options.
    3. Click on the Advanced Tab.
    4. Click on Reset.
    5. Check the box Delete Personal Settings, and then OK.
    6. Go back to Internet Options to the Advanced Tab, scroll down to Security and un-check "Check Server Certification Revocation" and "Do Not Save Encrypted Pages to Disk".
    7. Click OK.
    Reset Router

    Routers are the number one cause of connection issues for players of our games. In most cases of connection issues, the router is either blocking the ports needed to patch and play our games or is "clogged" and needs to be reset. Try turning off your router for 15 seconds, then turning it back on to see if this improves your patching process.
    Clear the LaunchPad Cache

    Navigate to the directory of the game you are trying to play and open the launchpad.libs folder. Delete thelaunchpad.cache folder and relaunch the LaunchPad again.
    Antivirus / Firewall

    You may want to make sure nothing is interfering with the LaunchPad such as a real-time antivirus scanner, a firewall, or spyware/adware on the computer. Add your game as an exception to bypass your virus protection software. Please check out the following articles for more information.
    Windows Proxy Settings

    To adjust the Windows Proxy Settings, which the LaunchPad uses to connect, please check out this article
