The .NET Framework 2.0 is not supported in NewsGator 2.0.  One indication of this problem is that you get the error message "Cannot Access a Closed Stream" when downloading feeds.

If you're running .Net Framework 2.0, you may need to force NewsGator to use Framework 1.0 or 1.1.  To do this, you need to create Outlook.exe.config, which will be in the same folder as outlook.exe, probably C:\Program Files\Microsoft Office\OFFICE10 or C:\Program Files\Microsoft Office\OFFICE11.  The contents of this file should be as follows:

<configuration>
   <startup>
      <supportedRuntime version="v1.1.4322"/>
      <supportedRuntime version="v1.0.3705"/>
   </startup>
</configuration>

RESOLUTION

This problem has been corrected for NewsGator 2.5.
