I check your script Jodle  and I have an idea. 
If you run HyperLobby as administrator and you set affinity to one core Lock On will be run on one core to!   
My OS is Vista x64 and I must run HyperLobby with admin privileges. 
If you open cmd script with admin privileges it starting in C:\Windows\System32>   
We need to modify script - show where HyperLobby is installed.   
Example for me:   
 
d:
cd Programy\HyperLobbyPro3
start "HL" /AFFINITY 2 /ABOVENORMAL hlpro.exe
   
Default HL install dir: 
 
cd C:\Program Files (x86)\HyperLobbyPro3
start "HL" /AFFINITY 2 /ABOVENORMAL hlpro.exe
   
Open notepad, paste this code and save as name.cmd   
It works for me. 
Remember to run script as an administrator.
