e-newsletter not available on sub-sites

Hi, I have installed the e-newsletter plugin on my site wpskillset.com.

1>

I can see the eNewsletter menu item on the mainsite, but the same is not available on the sub-site.

However I can see the following admin message on the sub-site:

"Please configure and install eNewsletter to use all available features. (dismiss)"

But when I click on the link in the admin message, the following message is displayed:

"You do not have sufficient permissions to access this page."

Please advise.

Is it possible to setup the smtp details at network level, so the users do not have to bother about the same.

Thanks, Best Regards,
Santosh
