Hi,

I've installed EPiServer CMO 2.1 using Deployment Center on EPiServer CMS 6 R2. Clicking Add campaign or Add test buttons in CMO interface, I'm getting the following error:

2013-04-26 16:39:49,106 ERROR [34] EPiServer.Global.Global_Error - 1.2.5 Unhandled exception in ASP.NET

I've installed EPiServer CMO on Windows 7 64bit (IIS 7.5), .Net 4.0 and Windows Server 2012 (IIS8), .Net 4.0 framework. On both machines I'm getting this error. I've tried to solve the issue using the following threads: http://world.episerver.com/Modules/Forum/Pages/Thread.aspx?id=54476 and http://world.episerver.com/Blogs/Thomas-Krantz-/Dates/2011/1/CMO-20-and-NET-4-installation-problems-and-solutions/ but the error still occurs. Anyone else have experienced similar problems?

Thanks.
