Campaign not sending

I searched all through the forums and see mention of the same or similar problem I am having.

Once I create a campaign and either Send newsletter now! or Schedule this campaign, under Recent campaigns it will say "Sending" and have the little spinning wheel going and going and going … but no send even after 30 minutes.

Able to send test email.

Modified .htaccess to include: php_value memory_limit 128M

Cron looks like this (I tested running with */1):

*/30 * * * * /usr/bin/php /home/username/public_html/sendy/scheduled.php > /dev/null 2>&1

*/5 * * * * /usr/bin/php /home/daveemai/public_html/sendy/autoresponders.php > /dev/null 2>&1

Any advice?

Thanks.

Dave
