I have installed courier to see if it will prevent us having to duplicate changes over multiple staging/live sites.  I have two sites set up on my local machine site1.localhost.com and site2.localhost.com with the appropirate entries in the hosts file.

When I try and transfer anything from site1 to site2 I get this error

Umbraco.Licensing.Exceptions.TrialLicenseException: Courier is running in Trial Mode, you can therefore only run it on your local machine, and only transfer to other local instances, non-local locations cannot be used

Both sites are local so why can I not transfer stuff between them.
