Cannot access any service through Sql Server 2008 Configuration Manager

I have SQL Server 2008 installed locally on Windows 7, The Configuration Manager starts ok but gives me the error "The server threw an exception. [0x80010105]". I have tried running the manager as administrator to no avail. Anybody any ideas? Cheers.

I had to install SQL Server 2008 SP1 to fix this problem. I guess it is an issue running on Windows 7 or the fact I also have SQL Server 2005 on this machine.
