This error happened with both Courier 2.7.5.1.90 and 2.7.7.3 (both umbraco v4 versions), installed on a Umbraco 4.7.2 installation.

I have tried installing and reinstalling numerous times, and clearing cache, yet i run into a "Index was out of range" whenever i go to advanced settings, or to be more precise:

-Right click on the content i want courier to package
-On the first screen where it asks you to choose "Yes, i want to transfer all children as well", i click on "Go to advanced settings" beside "Deploy"
-The next screen shows the "index was out of range" error with a stack trace.

Here is the stack trace:

System.ArgumentOutOfRangeException: Index was out of range. Must be non-negative and less than the size of the collection.

   at System.Web.UI.Page.RaisePostBackEvent(NameValueCollection postData)
   at System.Web.UI.Page.ProcessRequestMain(Boolean includeStagesBeforeAsyncPoint, Boolean includeStagesAfterAsyncPoint)

I have no idea why it does this, and it more or less ruins the purpose of courier. I have searched around, and one solution seemed to be to just remove Umbraco.Courier.CacheHandler.V4.dll, but that doesnt work either.

Any suggestions?

Oh, i have the license for the full courier if that matters.

EDIT I stumpled upon another piece of information. Is it true that i cant use the right click dialogue if i dont use webservice as the repository provider? Thats kind of a set back, as it's really easy with the right click, and our server setup does not allow direct http connection between umbraco installations.
