After installing Views module admin page disappears

Hi,

I have Drupal 5.1 on RH EL,

Apache/2.0.52 (Red Hat) Server,

PHP 4.3.9 (cgi) (built: May 4 2007 11:04:14)
Copyright (c) 1997-2004 The PHP Group
Zend Engine v1.3.0, Copyright (c) 1998-2004 Zend Technologies,

MySQL server version: 4.1.20

I am using Firefox 2 for browsing.

After successfully deploying Drupal I wanted to use the Organic Groups module. That requires Views module.
After the installation of Views after reload I get an empty page with nothing.
After manually deleting the Views module (views-5.x-1.6-beta5.tar.gz) from the modules directory I am again able to access the site.

It looks like a bug for me.

Please advise ASAP, since we want to use Drupal as an intranet portal.

Thank you.
