so im trying to upload my new game as a .rar file but it doesnt work. i spend 2-3 hours waiting for the upload process to complete and when it finally finishes, it says there was an error uploading the game. this is the biggest game i've uploaded to the site so far and, while the game was over 1 GB, the .rar file is only 616 MB. i have no idea how to use butler to upload because the guide is a bit too complex.

how do i upload games more effectively?
