Hi,

Just downloaded latest version of courier for Umbraco 4.10.1.  Installed it on both sites.  When I click the courier icon and select Deploy > Select an Item type > I select anything I receive an error:

System.NullReferenceException: Object reference not set to an instance of an object.
at Umbraco.Courier.UI.Dialogs.CommitItem.OnInit(EventArgs e)
at System.Web.UI.Control.InitRecursive(Control namingContainer)
at System.Web.UI.Page.ProcessRequestMain(Boolean includeStagesBeforeAsyncPoint, Boolean includeStagesAfterAsyncPoint)

A couple of things though:

I did have courier installed about 1 year ago and had it working.  I wasn't in a position to use it at the time but figured i could just in paste in the license and all would be well.  It didn't work so I uninstalled the old version and reinstalled the new version and noticed it left some things behind.  For e.g. I now see 2 of everything in the courier page.

Also, I don't use the root umbraco folder.  I didn't want others trying to access my customers sites via the umbraco/login.aspx path so I created a new folder and moved all of the umbraco files to there and changed the umbraco path in the web.config to admin.  So now customers can login /admin/login.aspx etc and now I'm wondering if this is whats breaking courier?

As a test I put the original Umbraco folder back with its files but still no joy.

I've tried several things but have run out of ideas.

The log doesn't reveal much either:
