Are you using an SP1 console to connect to an R2 Management Group?  If so, you’ll need to follow the below steps from the Release Notes (or upgrade your console to R2):

1.     Close the Operations console.

2.     On the Windows desktop, click Start, and then click Run.

3.     Type regedit, and then click OK to start Registry Editor.

Caution

Incorrectly editing the registry can severely damage your system. Before you make changes to the registry, you should back up any valued data that is on the computer.

4.     Browse to HKey_CURRENT_USER\Software\Microsoft\Microsoft Operations Manager\3.0\Console.

Caution

Ensure that you are not making changes to the HKEY_LOCAL_MACHINE version.

5.     Right-click Console, click New, and then click Key.

6.     Rename New Key #1 to ManagementGroupSessionManager, and then press ENTER.

7.     Right-click ManagementGroupSessionManager, click New, and then click DWORD Value.

8.     Rename New Value #1 to DisableServerVersionCheck, and then press ENTER.

9.     Right-click DisableServerVersionCheck, and then click Modify.

10.  In the Edit DWORD Value dialog box, in the Value data text box, type the number 1 (decimal, not hexadecimal), and then click OK.
