Riskle

Hi,
I have just installed this Pagination Component. But I can't get it to work.

It's giving the following errors:
Strict Standards: Declaration of Riskle_Db_Table_Abstract::find() should be compatible with that of Zend_Db_Table_Abstract::find() in C:\wamp\www\tellydb\library\Riskle\Db\Table\Abstract.php on line 336

Strict Standards: Declaration of Riskle_Db_Table_Abstract::_fetch() should be compatible with that of Zend_Db_Table_Abstract::_fetch() in C:\wamp\www\tellydb\library\Riskle\Db\Table\Abstract.php on line 336

Fatal error: Class 'Zend_Db_Select_Exception' not found in C:\wamp\www\tellydb\library\Zend\Db\Select.php on line 811

I checked the definitions of find and _fetch methods in Riskle_Db_Table_Abstract and Zend_Db_Table_Abstract.

Signatures from Riskle_Db_Table_Abstract are :
-- public function find($key) {
-- protected function _fetch($where = null, $order = null, $count = null, $offset = null, $cols = null, $selectParentFields = true)

And from Zend_Db_Table_Abstract are:
-- public function find()
-- protected function _fetch(Zend_Db_Table_Select $select)

Why are those defined in Riskle are different from those in Zend??

Please help me out !!
Thanks in advance,
Prasad K
