Hi Luciano, 
Did you first create the galaxyWeb security group? Instructions are available on usegalaxy.org/cloud under Step 1.

Hi,
   I am trying to run Galaxy in the cloud and  I am following your
screencast. I am having a problem when I need to choose the Security
Groups, there is only the default showing up. I don't see galaxyWeb. I
tried all AMI listed in your website and none worked. Then I proceed and
launch it. I copy and paste the public DNS, but it is not working (even
after 20 min). Is there anything that I might missing?

Thank you.
