Please assist, unable to add read/unread column

Aug 27, 2012 at 8:42 AM

I have successfully installed version3.ListItemReadUnreadSiteColumn.wasp on our sharepoint server, I installed via stsadmin.exe and it shows completed successfully.

When I try and add a column to a list I cannot see any read/unread option.

Any assistance you can offer would be greatly appreciated.
