Thanks you! The regions advice solved the problem for my friend who was getting 
the key pair does not exist problem. I am still getting the error:

ERROR:boto:400 Bad Request
ERROR:boto:<?xml version="1.0" encoding="UTF-8"?>
<Response><Errors><Error><Code>InvalidParameterValue</Code><Message>Invalid 
value 'null' for protocol. VPC security group rules must specify protocols 
explicitly.</Message></Error></Errors><RequestID>7ff92687-b95a-4a39-94cb-e2d00a6928fd</RequestID></Response>

This sounds like it could have to do with the access settings of the security 
group, but I don't know how to change. Any advice would be much appreciated!

One reason could be that the keys are in a different region. Need to create
the keys in us-east-1-North Virginia.
Cheers
