Recently, I installed Office 2010 and I migrated my Groove 2007 over to SharePoint 2010. On my PC, after installing the groove file, I am not able to open many files in my workspace. I am getting an error as "File Cannot Be Opened". Can anyone help me In this case, If yes than that thing will be great for me. On a new PC with Office 2007, This also happened to me once when I installed groove. I got tha same error for two months, after that it started working suddenly.
