Adam,
I am not exactly sure what you are asking me to do here. Here is some information that may help.
DotNetNuke is using a dll called SharpZipLib.dll - it is version 0.81.0.1407
You are using a dll called ICSharpCode.SharpZipLib.dll - it is version 0.84.0.0
When I bring each of these DLLs up in the Object Browser in Visual Studio, they seem to have virtually identical assembly information although I do notice that the exception handling object is different.
It seems that the only answer is to either rebuild the DNN core with the newer version or rebuild the cuteeditor with the older version.
Thoughts?
Cheers,
Scott
