I think you have to call Salesforce.com to enable your metadata API feature
But, to save your time, just login into the Enterprise Edition org and create a new package, and add whatever objects you want to deploy, then upload that package. Once the uploading success, you will get an installation url. Click the url, and log in as administrator of the Group Edition you want to install.I tried on both Managed and Unmanaged...they both work..
I just did similar deployment yesterday. Yes, you can deploy the custom objects from EE to GE. FYI, You can deply Apex Classes from EE to GE.
@Doudou, please tell me how to do it.
You can create a package, and add the objects you want to deploy to the package. Here is the guide on how to package and distribute:

Or you can deploy them using force.com IDE "deploy to server" option.
With deploying as a package, you can easily uninstall them later.
I tried using force.com IDE but am getting the following error:
