If you find a bug, take a look at the open issues. If it's not already reported, open a new one and attach the log.

If you're absolutely positively sure that you don't already have an instance of Headshot Box running then probably another program is listening on port 4000. In this case, edit the headshotbox.bat/headshotbox.sh file and change 4000 to whatever port you like.

It's either a bug or, if you're on Windows, you may have forgot to install Visual C++ Redistributable Packages for VS 2013.

Player List only displays players with more than 1 demo by default. You can change this in Settings -> UI Options.

No.

Yep. CEVO is barely really tested though.

See #65 (comment)

HeadshotBox counts all assists displayed in death notices. Valve awards assists more easily than ESEA (ie. you need to deal less damage to get it).

I don't know if it's possible to send playdemo commands (or any other request) to a CS:GO instance. As a workaround, you can have HeadshotBox kill csgo everytime you click the watch button in Settings -> Demo Playback.

• The watch button doesn't work for demo file names that contain the '~' char (gets expanded to the home dir) or spaces (sometimes it works, sometimes it doesnt. volvo pls)

• sudo dpkg --add-architecture i386
• sudo apt-get install -y libc6-i386
