Two easybook same site

[tonse]

I want two easybooks on one site.
This is what i tried:
1. Renamed ALL occurrrences of [easybook] to [ccsbook]
2. Renamed in ALl filenames [easybook] to [ccsbook]
3. Renamed in some directories [easybook] to [ccsbook]
4. Zipped all the files and tried to install.
In joomla I get the messages: Unable to write entry.

AM i forgetting something, or is it just not possible.

I would like to have two or more guestbooks on one site.
