Akocomment doesnt work!

[vlinhp2]

i installed AkoComment(1.4.6) on joomla 1.5.5 without errors, but it doesnt work. I follow theses steps:
- Enable Legacy mode
- Unzip AkoComment_Tweaked_Special_Edition.zip in a temp directory.
- install the bot and publish it
- install the component
- install modules
After installation, i don't see any link comments() at bootom of any article?
Please show me my mistake!
