So we are back to the same issues I mentioned with wrong/mismatched DLL
versions. For the empty list issue it seems to be a mismatched version
of Comcat.DLL
For more information about dll versions, such as determining what
product ships a certain version of a dll, check out the following link: http://msdn.microsoft.com. Click the Resource menu and choose DLL Help
Database.
Here are some possible solutions to the Comcat.DLL version issue.
