Getting charged Elastic IP - How to release or use it

Hi,

I'm using a TLKAPP server on AWS (via hup.turnkeylinux.org), and I've got an issue:

I'm getting charged for an un-used Elastic-IP.  

Now this is what I've done: 

Within the server section, I clicked on "Associate Elastic IP".  This gave me an error, saying that my server is part of a VPC, and therfore can't have an elastic IP associated.  I thought nothing more of it, until I got a bill.

Now I've looked through the EC2 section of AWS console and the VPC section, and neither seem to think that I've got an elastic IP allocated.

I also can't see any elastic IP management features within the hub.turnkey console.

If I select "Associate with Elastic IP" again, then I see that I seem to have one elastic IP, but I see no way to get tot he management features to release it.

Any Ideas?.
