Hi,

I am using Umbraco 4.11.7 and Courier 2.5 on Windows 7 x64.  This is a new install of Courier across local, dev and test servers.

I have created my first revision on my local machine.  When I click on it I do not get any nodes/objects listed, all I see are the Courier links for Compare and Install, Change Contents, and Transfer.

Clicking Change Contents gives me the following error:

CS0121: The call is ambiguous between the following methods or properties: 'System.Linq.Enumerable.Count<System.Collections.Generic.KeyValuePair<string,Umbraco.Courier.Core.RevisionItem>>(System.Collections.Generic.IEnumerable<System.Collections.Generic.KeyValuePair<string,Umbraco.Courier.Core.RevisionItem>>)' and 'System.Linq.Enumerable.Count<System.Collections.Generic.KeyValuePair<string,Umbraco.Courier.Core.RevisionItem>>(System.Collections.Generic.IEnumerable<System.Collections.Generic.KeyValuePair<string,Umbraco.Courier.Core.RevisionItem>>)'

Line 111:        //only enable 'package selected' button once there is something selected
Line 112:        function CheckMenuButtons() {
Line 113:            if ('<%= Revision.RevisionCollection.Count()  %>' == 0) {
Line 114:                jQuery(".classPackageSelected").hide();
Line 115:                jQuery("#noContents").show();

Looking in the courier/logs folder the only thing which seems to be of any relevance is this

I can't even get started with Courier at the moment.

Thanks,

Tim
