Error in manage category Magento CE 1.8

Question

I installed a fresh copy of magento CE1.8 on my system. I was able to add a few categories and products. But, all of a sudden the manage category page started showing an error

Fatal error: Class 'Mage_Adminhtml_Block_Catalog_Category_Tree' not found in C:\wamp\www\magento\app\code\core\Mage\Core\Model\Layout.php on line 491

I have not modified any code at all. Cant understand why this stopped working.

Try to run compilation process

compilation process copies all of the class definitions and code found under app/code into a singe directory: includes/src/ to increase magento performance. The performance increase is between 25%-50% on page loads.
