Thanks for this hack.. But I don't seem to get it working

(I must say that I'm a n00b @ vbulletin, but eager to learn)
I've first installed the hack, after that installed Delpih's new files to all the correct places ! But when I want to warn a member from the admincp. I get the error message:
Invalid User ID Input
Also I can only warn people in the admincp and not in the modcp.. When I log in to the modcp I only see:
View Issued Warnings
And nothing else..
Then my last (and probaly stupid question) but in the readme.txt It says to change some code in:
In Template postbit
and
Template postbit_legacy
But where can I find this Templates ?? :$ :$
Thanks in advance !
