I hope you don't mind but I took the liberty of fixing up the English in your Eng related files as there was quite a few translation errors - including the names of the modules still in German? (correct me if i am wrong) so this might explain why people have been having difficulty in realising that they are supposed to install modules in the ACP, as they aren't easily identified.
Anyway, I have fixed up the includes/acp/info/acp_kb.php, and language/english/mods/kb.php files for you and they are located here.
In order for the new Modules to be used with the English names, the previous German ones need to be removed from the ACP and reinstalled (after the altered acp_kb.php file has been uploaded) for those who have already installed them previously.
The only line I left intact in kb.php that may still need translating properly is the following:
'KB_DESCRIPTION' => 'If you yourself have written an article, you can play him at the end of the page to submit an audit after the article we will publish it here. ',
Sorry but I cannot work out what this is supposed to mean, so don't know what to change it to in English
But I hope the other files come to good use.
