Then check -bloodlines/vampire/cfg/config.cfg. You can edit this file with any text editor. Look for the line
bind "MOUSE2" "vdiscipline_last"
If there is no bind "Mouse2" line, put this in. If there is another command bound to mouse 2, overwrite it.
Also check autoexec.cfg for any bind mouse2 commands in an ALIAS function.
If there is the right bind mouse2 command in config.cfg, and no ALIAS to change it in autoexec.cfg, then I don't have any idea.
