[Typo3] Extended calendar

[Parul]

Hi List,

I have been evaluating some calendar extensions. I installed the Extended Calendar-calendar extension. Associated this frontend plugin with a page but in the frontend it gives me the following error:
'NO entry in the $TCA-array for the table "tt_news". This means that the function enableFields() is called with an invalid table name as argument.' .
How do i resolve this ,any pointers????
Thanks in advance,

Parul
