Hi there

I have Umbraco 4.7.1.1 installed and installed Courier from the Umbraco Pro section of the Umbraco Package repository yesterday. The version installed is showing as 2.7.

I have nForum and uWebshop installed.

If I try to published anything from the content tree or the uWebshop tree I know get the following error and stack trace in the CMS:

Could not load type 'Umbraco.Courier.Core.Cache.ItemCacheManager' from assembly 'Umbraco.Courier.Core, Version=1.0.4373.24831, Culture=neutral, PublicKeyToken=null'.

The stack trace references a folder that is not on my PC.

If I run a build of my project in Visual studio 2010 the build is successful.

Am I missing a key file?
