Are you able to run any ec2 command line tools (like ec2-describe-images)??
A lot of times it's the private key file readable by group or others.

I've copied the AWS info into the config file from 
my amazon AWS credential page  but it seems I am still unable to authenticate my AWS account with starcluster.
jtaylo_at_gkf-ubuntu:~$ starcluster start mycluster
StarCluster - (
http://web.mit.edu/starcluster) (v. 0.92rc2)
Software Tools for Academics and Researchers (STAR)
Please submit bug reports to starcluster_at_mit.edu
!!! ERROR - AuthFailure: AWS was not able to validate the provided access credentials
Any suggestions to find out which part of my AWS info is causing problems?
Thanks,
Jonathan
