You agree to the terms of service by downloading the launcher. The launcher will download all the required files needed to run the game. If you are experience issues, please visit the boards help section.
Note: Sometimes when we release an update some antivirus programs take 96 hours before they recognise our files as being safe. Longer term will be solved by purchasing an expensive certificate, of which we'd be grateful for any donations to help us achieve this sooner. If you need assistance with your AV please jump on Discord or ask for support on the forums!
