I think there is the problem with session cookie with the chrome browser. So just go through this directory /app/code/core/Mage/Core/Model/Session/Abstract/Varien.php file and comment out the line from 85 to 92 in magento (1.7.2 for my case). Like this // session cookie params /* $cookieParams = array( 'lifetime' => $cookie->getLifetime(), 'path' => $cookie->getPath(), 'domain' => $cookie->getConfigDomain(), 'secure' => $cookie->isSecure(), 'httponly' => $cookie->getHttponly() ); */ And use your credentials to logged in. Hope that should works for you!!!
