Emm...what exactly didn't work there? If you use that one, It doesn't automatically spam the trigger, it is just enabling the fast-trigger, which can be used by the key set under "Settings", standard "X".
Could you pleaese do me a favor then? If you know a bit of Cheat-Engine, pls try the following:
Search for the value "100" with cheat engine, get hit by a zombie, search for "decreased value", regenerate, search for "100" and so on, until you only have a few offsets left. One of them should be sth like 01BDB(XXX), pls tell me that one so i can make it work again (don't have the original here ;( )
