All attempts to reach EC2 instance time out

I've been struggling with this for two weeks. I am trying to set up an application in AWS, but cannot reach the EC2 instance. I've tried using the Visual Studio publication package, building an environment in EBS, building a server in EC2, connecting to the site via DNS and public IP, both in a browser and with ping, curl, trace route, and last with a RDC. I've tried nearly every combination of the above, and it seems like I am getting stuck on a firewall, somewhere. Trace route ends on 54 or 205, which belong to Amazon.

The obvious solution seems to be that I am not using security groups correctly, but nothing seems to work. I've tried opening up TCP, HTTP, SSH, HTTPS, UDP, and RDP, both to all addresses and my own IP, as well as opening up the scary All traffic from Anywhere. I usually just alter the group listed in the EC2 instance description, in the EC2 console, but have tried changing everything that is not an AWS group with the "Do not change or delete" warning.

I've only been developing for a couple of years, and assume that I'm missing something obvious, but I've never had this much trouble with hosting, and am completely stumped.
