It is kinda odd that people have to make a script to add to the game directory to have auto run. Then they have to worry about being blacklisted for altering game files.
An easy way around that is if you have a gaming Keyboard, Mouse or even headset that has Programmable Keys!
I use a Logitech G 15 Keyboard and this is the Toggle Macro that I made and assigned to a G key and now I have auto run!
Just make sure that you have time in between the depress and release, delay set to 0 and the macro is set to repeat and Toggle on and off!
