Resolved trough contacting support, Here is the mail:
Anyone else with this issue, try:
Please try using the instructions below to prevent background applications from automatically starting with Windows as this can often causes issues like the one you reported. Please note, this process will not uninstall any applications from your computer (just prevent these applications from automatically starting when Windows boots up).
To do this:
Press and hold the Windows key and then hit the R key. This should bring up the Run dialog box.
Type “MSCONFIG” without the quotes, and click “OK.” This should open the System Configuration Utility.
Click on the “Services” tab and check the “Hide All Microsoft Services” check box near the bottom, then click the “Disable All” button (You MUST click “Hide all Microsoft Services” to avoid deactivating essential programs).
Next go to the “Startup” tab and click the “Disable All” button.
Once these items are all disabled, click the “OK” button and you will get a prompt to restart your computer. Please restart your computer.
Once you return to Windows, please try connecting to the game again.
To reverse these settings, simply run MSCONFIG again and click “Normal Startup” on the first window labeled “General.”
Note: If you need a specific application to run upon Windows startup but still want to use MSCONFIG, just follow the above instructions and on step 4, re-check any application you feel needs to start with Windows. Examples would be wireless connection software, mouse or keyboard applications or even security applications. Please note that security applications can often be a contributing factor to issues such as the one you are experiencing. If you haven’t done so already, please also temporarily disable any Anti-virus, Firewall or other security applications for testing purposes. While we do not recommend running your machine without a security application, should disabling the software help resolve your issue we can reinstall it and work to configure the application so it doesn’t cause problems.
Please do not hesitate to contact us should you have any additional issues, questions, or concerns.
