Private Instance on Amazon EC2

[assortmentofsorts]

Hello All,

I have setup 2 instances (1 m1.small: "IE8 - ami-8a6c9de3 : webpagetest-us-east/ie8-20110113.manifest.xml" and another running on ubuntu which has the webserver setup).

While creating the windows instance from the image I added the wpt_server userdata string and modified locations.ini:

[locations]
1=EC2_Virginia
default=EC2_Virginia

[EC2_Virginia]
1=ec2-us-east-IE8
label="Amazon EC2 East ( Virginia )"

[ec2-us-east-IE8]
browser=IE 8
latency=4
label="Amazon EC2 East ( Virginia )"
localDir=/var/www/work/jobs/ec2-us-east-IE8

It doesn't seem to work though. I get an error while trying out on the private webserver : "Error sending url to test machine. Please try back later " Is there anything else that I might have missed out on? How do I access the windows instance? Sorry but I have no experience with hosted windows instances. Should I point the URL in urlblast.ini to the IP of my webserver?

Thanks!
