Ah, that's right, my bad. It should be "hack", not launcher. Fixed. The "# Start hack." is a comment.
I've uploaded the fix to the site as well.
As for $preset_estimate_max_load - please read the instructions carefully, or watch the video again.
You have to replace an existing preset in the case that adding a preset doesn't work. Also, if your camera is CRC01, you should be able to use applaunch, since it isn't signed.
To check whether the hack is running, you can connect to the camera via telnet and run "ps". "hack.exe" should be in the process list.
