Error in Management Studio

Have installed SQL 2008 db engine and client tools. Each time I attempt to return a resultset, I receive the following error:

An error occurred while executing batch. Error message is: Method not found: 'Void Microsoft.SqlServer.Management.UI.Grid.ColumnInfo.set_ServerVersion(Int32)'.

This error occurs on any data access, such as:

select * from sys.columns

Does anyone know what might be going on?

And if you switch results to text instead of the grid, does everything work?

No, I receive the same error:

An error occurred while executing batch. Error message is: Method not found: 'Void Microsoft.SqlServer.Management.UI.Grid.ColumnInfo.set_ServerVersion(Int32)'.

|||Nope. Do you have more than one machine to do this on, or could you re-install SSMS?

Had same exact error message. Tried uninstalling and reinstalling just the client tools with no affect. Then completely uninstalled SQL 2008 (had both June and July instances) and reinstalled all of July. This "fixed" the problem. This is a frustrating one, I'd already submitted it as a bug earlier today. Perhaps it is related to partial uninstalls of just the client tools, since I had to uninstall the June tools to install the July ones the first time around. But doing a total remove of all of SQL 2008 seemed to do the trick.

Have Fun!
