[TYPO3] extension efaq has crashed my installation

[Nagita Karunaratne]

Hi,

I have my first real crisis. After installing the extension 'efaq' I get 
this intractable error:

TYPO3 Fatal Error: Extension key "div" was NOT loaded! 
(t3lib_extMgm::extPath)

And I cannot get the BE to appear.

The only solution I see is in German and I only speak English:

IS there any way to restore or fix this problem?

Thanks,
Nagita
