Activation Key error

License key is:
2025c56a04d5a838008cbe6618723273

When I try to add the license I get the error below:

Activate license
Unexpected Error! The query returned with an error.
The following message was returned from the server:

Also curious if it is ok to have the license in staging and production with same domain? staging.esassoc.com and www.esassoc.com
